iPhone

iPhone's 5th Birthday: The Most Successful Disruptive Innovation. Ever.

Five years ago Apple introduced the iPhone. On the eve of it's introduction, I published a blog article predicting that it would cause massive disruption of several industries and the reasons why.

We predicted it would sell beyond Apple's expectations, and beyond what even the most optimistic analysts projected. It turned out that as bold as we were, we weren't bold enough in predicting how successful it would be.

We predicted it would knock the Blackberry from it's perch as the top (business) smartphone. A prediction that many scoffed at -- especially the executives at RIM.

There were other predictions as well which we'll leave you to read if you're interested.

Although these things seem obvious in retrospect, I made these predictions based on disruption theory, and took a big step out of line, disagreeing publicly with my business colleague at the time, Mike Urlocker, with Clay Christensen, the father of disruption theory, and with other notable marketing experts including Al and Laura Ries -- renowned for their work and books on positioning.

Unbelievably disruptive: iPhone's Accomplishments

While the iPhone today has stiff competition from another disruptor -- Google's Android, and especially the leading purveyor of Android (Samsung), it remains the trendsetter with a list of remarkable accomplishments:

  • iPhone alone is a bigger business than Microsoft, once considered the unassailable titan of tech based on its Windows and Office franchises. The same Microsoft whose monopoly market power was considered so strong that the DoJ targeted it with antitrust suits that threatened to break up the company. It's also the same Microsoft whose CEO, Steve Ballmer, mocked Apple for thinking anyone would buy a $500 phone. Who's laughing now, just 5 years later?
     
  • The iPhone has generated over $150B revenue since its release, and has shipped over 250M units.
     
  • At the current run rate, the iPhone will generate about $35B in profit this year. Only one company on the planet (besides Apple) generates more profit than the iPhone -- Exxon Mobil.
     
  • RIM and the Blackberry are on the ropes, probably breathing their last. RIM announced they are laying off nearly 40% of their employees yesterday. The same RIM that as recently as two years ago was still claiming that no one would buy a business phone without a keyboard, and that it had an unbeatable advantage with corporations because of its security features.
     
  • Nokia is also on the ropes. And, most competitors in the PC business have suffered serious setbacks, including Microsoft, HP and Dell. All either as a direct result of the iPhone, or because of its Trojan Horse effect (which my article in 2007 predicted).
     
  • iPhone plus its big brother, the iPad, have made Apple the most valuable company on the planet, completing a 15 year disruptive comeback from near bankruptcy. Sitting on par with Exxon Mobil in market cap just 4 months ago, Apple is now valued at nearly $120B more, and by traditional multiples for "growth companies", could easily be valued at 2 to 3 times more than it currently is. It will likely become the first company in history to have a market cap exceeding $1 trillion within the next 18 months.
     
  • Apps, apps, apps. How many companies owe their existence to the App Store and the rest of the iPhone ecosystem? There are over 600,000 apps available in the App Store -- 600,000 products that wouldn't have existed but for the iPhone. As of March of this year, more than 25 billion apps had been downloaded.

On the iPhone's 5th birthday, we hope that Steve's untimely passing doesn't mean the end of Apple's exceptional innovation and market leadership. The world needs more companies like Apple that anticipate what we want and how we want it, even before we're able to articulate it. Companies that push for what's next, instead of simply copying the best of what's out there (Samsung).

The iPhone isn't just the most disruptive innovation ever, it is symbolic of a state change in what we expect from technology and how we interact with it. It's hard to imagine how different the world was six years ago, almost as hard as it is to remember how we survived without the internet and email.

What does the future hold?

Looking forward another 5 years, we wonder:

  • whether Apple can continue its remarkable run of industry-disrupting innovation without Steve?
  • if the iPhone will still be on top, or will Android catch and pass it?
  • what new innovations are still waiting to come out of Apple that will change the world as we know it -- is there a TV coming? what about home automation? cars? social media? Or, is the era of great new things from Apple over?
  • who will pick up Steve's baton and run with it?

What do you think?

Updates

Disruptive Tidbits: iPhone Update, Office 2007, Disruptive Marketing, and more

A collection of disruptive thoughts, observations, and small items not big enough to rate their own articles:

iPhone Predictions Already Exceeded

The day before its launch, we wrote a lengthy analysis of the iPhone's disruptive potential and published our predictions of its likely popularity. Many disagreed, but our expectations were pretty close to bang on, with Apple announcing 1 million sold just 74 days after the initial release.

Some fanatics might have suggested even better sales possible, but this is about the top end of what one would expect for a disruptive product. The usual pattern is to seep into the market relatively slowly and then really take off as subsequent versions add features and correct problems, becoming good enough for more and more people until they reach the tipping point and explode into mass market consciousness.

With the unparalleled hype about the iPhone, it's not surprising that it was strong out of the gate, despite many noted complaints about all the ways it wasn't up to snuff (also very common for new disruptive products).

And a New iPod Too

The new iPod Touch is an iPhone, without the phone.

The new iPod Touch is an iPhone, without the phone.

We also discussed the likelihood of a family of mobile handhelds using the iPhone platform, and already we have the next generation iPod, which not surprisingly is an iPhone without the phone. 

Along with that new product came a brilliant move of partnering with Starbucks to offer free Wi-fi access at any of their locations. 

It's actually pretty smart for both sides, as the days of charging for a Wi-Fi connection are almost over. This is a way for Starbucks to be a bit ahead of the curve and benefit from the glow that surrounds the iPod and iPhone.

Watch for iPhone Sr. coming soon to an Apple store near you -- I expect it will be outfitted as a true business-oriented handheld, with connectivity to corporate systems, better security, more horsepower, a suite of office applications (note that Apple's iWork product was also upgraded over the summer to offer a spreadsheet tool for the first time and integration with Office 2007. 

With the "holy trinity" of word processing, presentations and spreadsheets now covered, the Mac becomes a lot more viable as a PC replacement, and will suddenly be "good enough" for many who've been waiting for a real Microsoft alternative, and the iPhone also gets closer to being a viable substitute for the notebook, especially for road warriors tired of airport security hassles.  Don't know if we'll get it before Christmas, but I promise, the writing is on the wall. 

Office 2007 UI Mistakes: What Were They Thinking?

Microsoft is probably wondering about some of the horrible mistakes made in Office 2007, such as imposing the "Ribbon" interface on power users who not only don't need it, but find that it slows them down. Personally I don't like it because it is a big keystroke waster, makes it hard to find all the things you knew, and it wastes a ton of screen real estate.  Not offering an option to use the old menus or the keyboard interface was a really bad idea.

Microsoft's Office 2007 "ribbon": Seriously, someone thought this inelegant, productivity-sucking mess was an improvement!

Microsoft's Office 2007 "ribbon": Seriously, someone thought this inelegant, productivity-sucking mess was an improvement!

Although the XML underpinning was a great idea, it also makes it easy for someone like Apple who is better at tools to eat Microsoft's lunch, and with such a huge change in the interface, there's plenty of incentive, and what has anyone got to lose by giving Apple's products a try? 

It's a classic case of overshooting the users' needs on the one hand, and not fulfilling them on the other.  And, it's the kind of arrogant decision that could only come from going so long without real competition.  Ripe for disruption indeed!

Relationships

For many, summer is a time to re-connect with family and think about relationships. Of course, we did that too, and got to attend that rarest of events -- my parents' 50th wedding anniversary.  Even more amazing, my wife's parents celebrated their 50th a couple of years ago.

How many people can say that their parents and in-laws are not only still all alive, but have both managed to stay together for 50 years?  There must be a pot of gold at the end of a rainbow somewhere.

And, check out the picture.  Gotta love the skinny people and skinny ties.  They just don't make them that way any more.

Disruptive Marketing

In the category of "growing realization of the obvious", there's another sort of relationship that comes to my mind. Namely, the relationship between marketing and disruptive innovation. With a couple of decades of technology marketing experience behind me, and my focus on disruption, you'd think I would have spent more time considering the connection. It's a relationship that's lived in my head without expression.

Strangely, Christensen comes close to alluding to it a few times in his books, but never really addresses it.  In fact, it's almost as if all those innovations that he describes were so obviously fantastic products that they grew to dominate markets without anyone making the smallest effort to target the right niches and make them appealing to customers.

I've been developing some hypotheses about that relationship, and gathering evidence and observations to test them. It's a simple but profound notion. Namely, that disruptive marketing is the secret sauce that takes the potential of a disruptive innovation and turns it into a reality.

Yes, there are accidents along the way, and occasionally disruption happens without intent, but it's become increasingly clear to me, both by looking at missed opportunities for disruption, and at products that succeeded in turning the tables, even against the odds, that disruptive marketing is a necessary component.

I will be delving into this idea in more detail in future posts with case studies, examples, definitions, and description of how disruptive marketing works.  I hope to elicit a healthy discussion around this idea and get "war stories" from marketers about how they did it, and what disrupts versus what is plain vanilla.

Upcoming Presentation

Carrying on with this idea, I will be making a keynote address to the International Marketing Congress in Lisbon in a few weeks.  The conference theme is The Disruption Point, and I will be addressing the connection between Disruptive Innovation and Disruptive Marketing. 

This will be the first public forum where I will be presenting my theories and observations, and I'm looking forward to a great discussion and debate.

Disruptive Business Strategy: What is Steve Jobs Really Up To?

Two days before the official launch of the iPhone, the pitch of media, pundit and public anxiety over perhaps the most anticipated new product since Windows 95 has reached a level only Steve Jobs could properly describe -- Insanely Great!  And here I am, contributing to the noise, raising it even a decibel louder if that's possible.

How loud is it?  As I finish writing this post, Technorati says that there are nearly 189,000 blog postings (in English -- there are nearly 305,000 in all languages) that talk about the iPhone. 

iPhone Debut Rivals Harry Potter Mania, But Will It Last and Why?

Compare that with 39,170 that mention Motorola's RAZR, a phone that was the previous biggest smash hit and which literally put Motorola back in the cell phone business after years of decline.  Nearly 6 times the level of mention of a phone which has been exceedingly popular, a design hit, has been in the market since 2004 and which exceeded all other flip phone sales within one year of its release. 

And, the number of postings that include mention of the iPhone has been rising by over 1,000 every 4 hours today, and you can count on it growing even faster until the pent up hysteria is released at 6pm on Friday.  And, the chatter certainly won't stop then.

Every major media outlet has weighed in.  The Wall Street Journal, New York Times, USA Today, every computer or telecom related industry trade journal has reviewed it.  Virtually everyone who's been privileged to receive one of the media samples for review has said it's cool -- so cool it almost lives up to its hype. 

Like the mania for video game consoles or Harry Potter books, prospective customers started waiting in line outside flagship stores in New York Tuesday morning.  Unprecedented for a phone.

Think about it -- the entire country seems locked in a heat wave, with most major cities experiencing temperatures in the mid 90s or higher.  Yet, people are so lustful of being one of the first to own an iPhone, that they will camp outside a store for 4 days in the sweltering heat to lock in to a 2-year service commitment from AT&T, the worst service provider in the business (more on that later).

So, does all this mean runaway success -- the game is already won?  Or, will there be an equal and opposite reaction when possibility and excitement about the future gives way to reality, and inevitable issues with service, availability, bugs in functionality and unfulfilled expectations?

Apple fanatics say it will be successful because it is ultra-cool, easy-to-use, a breakthrough in design elegance and software sophistication. Naysayers say nothing could live up to this level of hype, and that when things die down, sales will appear lackluster no matter how good they are.

Virtually everyone notes the stupidity of getting into an exclusive deal with AT&T and warns that this could be the albatross around the iPhone's neck. Almost all of the speculation and predictions are based on visceral and emotional reactions, and influenced heavily by the reality dispersion bubble that surrounds Steve Jobs, and by the majority belief that "better" wins. 

But if we run with that notion reductio ad absurdum, what exactly does 'winning' mean?  Assuming that the consensus is that the iPhone is a better phone, does it have to achieve market dominance as a late entrant the way the iPod has in the MP3 player space?

Surely it doesn't have to match iPod's 80% market share within 5 years! There are over a billion mobile phones already in use around the world.  Is a 10 or 20% market share strong enough to be considered successful? (The RAZR's share is only around 5%.)

Is this even the right yardstick to use?

The iPhone Will Be a Disruptive Winner

iPhone will be successful regardless of the metrics used.  It will be successful beyond the expectations of the most enthusiastic pundits. 

It will be successful beyond what Steve Jobs thinks.  It will be successful in spite of the apparent deficiencies that have already been noted in the reviews. It will be successful despite partnering exclusively with a single carrier, and the one most despised in the industry -- although this will be the biggest road bump the iPhone faces

It will be successful because it will change the game -- actually, it will change many games, and therein lies the secret of its success.  It will do all this because it will be disruptive. 

But, predictions are dangerous. And, mine disagree with those of many people whose opinions I respect and whose theories I borrow from. Even though I'm siding with the majority who believe the iPhone will be a big winner, how do I arrive at that conclusion and what exactly makes it disruptive?

Who Disagrees With Me

Before explaining what the highly respected experts are missing, let me first say who some of them are and try to summarize their positions.

Innosight

Innosight is the consulting company formed by Clayton Christensen to sell management services around disruptive innovation. Clay developed the original ideas and theoretical framework that underlies disruptive innovation in his series of books - The Innovator's Dilemma, The Innovator's Solution and Seeing What's Next. Saying he (or his minions) have it wrong is like saying that the pope isn't Catholic.

In January, after the original announcement of the iPhone, Innosight consultant Jonathan Barrett said:

  • at $500 or $600, the price is too high
  • Cingular (now merged into AT&T) is incapable of providing the same high quality, seamless user experience that Apple customers expect
  • iPhone won't work on 3G high speed data networks -- only EDGE or Wi-Fi is supported -- so there won't be anything unique or distinctive about the wireless service
  • the deficiencies plus high price point will prevent iPhone from finding a market sweet spot
  • the approach of Apple is a "sustaining strategy" (i.e. incremental innovation of the cell phone), not a disruptive one, positioned against deep pocketed, long time industry incumbents who have a lot to lose if Apple wins and will fight fiercely for share

He reaches his "not disruptive" conclusion while still finding many things to like, such as lack of keyboard, design beauty, novel interface, thinness and coolness factor.

Mike Urlocker

My colleague, and the CEO of The Disruption Group, has a stronger technology, industry and investment background when it comes to the iPhone, having been the original analyst at UBS to identify the RIM Blackberry as a disruptive product and the first to recommend RIM as a strong buy. Mike has worked for and advised software companies on marketing strategy, and at UBS he was executive director and member of the global technology and telecom teams.

In his Disruption Scorecard evaluation of the iPhone, again shortly after the original announcement in January, Mike rates it a B-, and labels it likely a hit, but not very disruptive.  He reasons that the product appeals to people who want status and high design (the coolness factor) and are willing to pay for it, but that it doesn't have much potential to change the game like Blackberry did, or upset incumbent rivals such as Nokia, Motorola or Samsung.

Laura and Al Ries

Branding and positioning experts Laura and Al Ries (Al Ries and Jack Trout wrote the original book that defined the concept of positioning) take a different tack, identifying the iPhone as a "convergence" product, and the iPod as a "divergence" product. The concepts of divergence and convergence come from Evolution Theory -- basically, the idea is that there is a common origin to all species, but that over time the "tree of life" diverges as natural selection creates specializations to adapt to the environment.

Another failed convergence product.

Another failed convergence product.

Similarly, Al and Laura (and other pundits too) argue that the natural trend for all products is towards divergence and specialization to better suit consumer needs.

They claim the iPod was successful because it was a divergence product. Moreover, they argue that most "convergence" products fail -- convergence being when multiple feature categories are combined in a single product (in iPhone's case, an iPod, cell phone and PDA).

Their position is that consumers prefer products that are optimized to do one task well, rather than a lot of tasks poorly, and they further claim that the iPhone has been over hyped and most over hyped products fail to live up to expectations, therefore the iPhone will be a failure.

Hmmmmm.

Most of the others who claim the iPhone will be a failure base it on their own personal biases rather than what the market as a whole is likely to do and why -- "I'm not going to get one because . . .".  Name your complaint here. Price, lack of keyboard, slow data network, AT&T as carrier, touch screen keys too small to hit accurately, it will have bugs in version 1.0, etc.

So, what are they all missing, and more to the point, what is Steve Jobs really up to?

The Label Problem

One of the problems with evaluating anything analytically is that we get hung up on labels rather than thinking about what the labels mean and why the rules of thumb associated with them usually work. In the case of the iPhone, there are many labels and definitions being applied that are throwing people off the scent of what's really happening and my belief is that this is deliberate.

Yes, Steve is trying to fool the experts and fly below the analytical radar, ironically while mounting one of the most pervasive and successful hype build ups of all time.

To start with, the name iPhone is a mislabeling. While iPhone does indeed have phone capability in it, it is not a phone. Suspend disbelief for a second, walk with me a little, and it will all make sense soon.

Is your laptop PC a phone because you can make GoogleTalk or Skype calls using it? If not, why not?

Does it matter that it isn't the only thing you do with it? What if that was the most important thing you did with your PC, because you make a lot of calls to India, and free long distance service is worth a lot to you? Still not a phone?

Well, if your PC isn't a phone, is it a typewriter? I know that the primary purpose for my PC is typing documents, blog posts and html. I print a lot of those on paper. Mine is definitely an evolved typewriter.

Or maybe your PC is really a gaming console, or a mobile email device because you use it at home, at work, at Starbucks and at hotels and other wi-fi hotspots around the world to send and receive emails. Or, maybe it's just another example of a highly unsuccessful convergence device?

Or, do you still think your PC is something else?

The iPhone is Definitely Not a Phone

So, if you were willing to suspend disbelief and suppose that the iPhone might not be a phone, what is it then? Let's start with why it's called an iPhone.

iPhone is both sales positioning and a ruse. iPhone is positioned as a phone because Apple knows that in that niche, the market is sorely lacking for a stylish, easy to use, fun, visual, well-designed and well integrated device. It is a first if only because of its elegance. Don't believe me?

Then why isn't it really an evolved iPod?  One with a really big screen, beautiful graphics and music navigation, and by the way, it includes the ability to make phone calls?

The reason is because Apple believes this is the purpose that you will understand out of the starting gate, and for which it can convince people to shell out $500 or $600 to get the most stylish and coolest gadget on the block. Therefore it is positioned as a phone, and that's the basis on which everyone is analyzing it, and writing glowing reviews. But it isn't a phone.

It's also a ruse, because Mr. Jobs has a much higher goal in mind than selling the world's coolest phone. But this is an effective way to divert attention from the real disruption that is happening until it's too late.

Why This Makes Perfect Sense

Let's get a historical perspective to make a little more sense of this. When Alexander Graham Bell invented the telephone and tried to sell his patents to Western Union in the late 1870s, how do you think he described what it was?

No one had a framework to describe how revolutionary the phone would be as a communications tool. If you wanted to talk to someone, you went across the street, knocked on their door, and if they were at home or in their office, you could talk.

Initially, outside of the securities industry, people couldn't even understand why they would want a phone. Especially since the first version could only work over short distances due to signal loss on the wires. There was no network, there wasn't any need for communications to be sped up that much and nobody else had one, so how much use was it?

Bell considered the telephone to be a way to transmit voice over the telegraph, and that's why he thought Western Union would buy his patents. Bell viewed the telephone, perhaps one of the most disruptive technologies of all time, as an incremental ("sustaining") innovation over telegraphy.

Western Union, on the other hand, viewed it as being worth less than $100,000 since they rejected the offer to buy the patents for that much, although they later tried to buy them for $25 million.

Do you consider your telephone today to be a highly evolved telegraph? If you can imagine that, what about your cell phone, or is it different because it's mobile? What then of the iPhone? Just a space age telegraphy device with no keys or dials?

The important thing to note here is that in the early days, it is difficult to imagine the application and importance of disruptive innovations if they really are, because no one has a framework to understand its value.

That's why the car was positioned as a horseless carriage. That's why TV was radio with pictures. That's why the first computer was called ENIAC -- or the Electronic Numerical Integrator and Calculator. 

That's right, the first computer was just a calculator that cost 200,000 man hours to build, $486,804 in 1946, and used $650/hr worth of electricity to sit idle. Some times the original naming belies the importance of an innovation.

So, positioning of an innovation in the short term is not the same as long-term recognition of value and the salient characteristics that define its use. If not for the need to calculate missile trajectories more quickly and accurately during the war, the first computer might never have been built.

And what of convergence versus divergence? Most consultants and branding experts will tell you that convergence as a strategy almost always fails, because the more things you combine into one, the more compromises you have to make in design, and each individual function is sub optimized at the expense of the whole.

In disruption theory, a parallel idea says that as companies continually add sustaining innovations to better meet the needs of mainstream consumers and/or differentiate their products, they eventually overshoot the needs of most of their customers. Convergent products usually exceed the needs of all but a small minority of any prospective customer base. After all, who needs every tool on a Swiss Army knife?

That's the theory, but the reality is that when you try to apply simplistic labels to categories or products and then assign attributes or success factors based on those labels, you can miss the forest for the trees. In the case of convergence versus divergence, this is especially true, since which bucket you assign a product to varies based on whether the combined elements are truly synthesized in such a way that they cannot be separated and provide the same benefit, or whether they are just bolted together and not really integrated to optimize overall performance.

Ask yourself whether the combination of radio technology, speakers and a cathode ray tube to make a TV represents convergence or divergence? Is it the evolution of radio, or are the elements synthesized in such a way that they create something truly new?

If I turn on the TV, but listen to it from another room, is it still a TV, or is it a radio? Did the TV fail because several technologies converged? What about personal computers?

So what is the iPhone, and what is Steve really up to?

It's a handheld one of these. Fits in your pocket too.

It's a handheld one of these. Fits in your pocket too.

The iPhone is disruptive because it isn't really a phone, or for that matter, an iPod. If it was either of these, then as cool and elegant and nicely designed as it is, it would still just be an incremental or "sustaining" innovation.

Remember that the iPhone has a complete version of the Mac's OSX operating system embedded, plus it lacks a keyboard and has a truly novel interface with seamless integration between different functions. With all that, it can be considered as the first truly personal handheld entertainment and communications computer.

It can also be considered the first handheld business computer powerful enough to replace a notebook for road warriors tied of lugging all their paraphernalia through airport security. In other words, it competes in a different class of products -- not as a phone, not as a smart phone, and not as a computer.

It serves the un- or underserved need for lightness, simplicity, ease of use, true integration and is simple enough that my mother could use all the features without thinking about each being a different application or device. Competing against laptops, it doesn't yet have all the applications my PC has, but it is "good enough" that many will be ready to give it a try.

And, there are already numerous applications you can download to enhance the functionality for your needs, and many more business applications (especially things like bluetooth connectivity to a real keyboard, document editing, spreadsheets and presentation capability) which will run in Safari are likely to come. 

And, when compared to a laptop, it is disruptively inexpensive. Analogous statements are true if you evaluate it as a personal communications and entertainment computer.

This is, I think, what the huge excitement is about. People innately sense that this is much bigger than a phone, they just aren't yet able to articulate what is significant about it, and how we'll look back on Friday June 29, 2007 as one of those days when everything changed. 

And, it looks really cool and I desperately want one.

Steve's End Game

The iPhone is a trojan horse.

Steve lost the first battle between the PC and the Mac because he was less sophisticated as a business person in those days, and didn't fully appreciate how difficult it would be to convince the masses that they needed an expensive personal computer before they had even used one at work. In 1984, the Mac exceeded the needs of most potential customers, and looked like a toy to business (unless your business was about graphics or publishing).

The DOS-based PC was the "good enough" disruptive innovation of its time because it catered to mainframe users used to buying computing equipment from IBM and used to looking at green-screen character-oriented terminals.

This time it's different. Almost all of us use PCs daily. And, most of us are tired of the now clunky-seeming interface which isn't much different or easier to use than the initial Mac interface of more than 20 years ago.

And, we desperately need a single, small pocket-sized device that can handle all our business needs while on the road and enable us to leave our 10 pound paperweights at home. Something that's easy to get through airport security, and makes my life less complicated.

Moreover, at the price point of $500 or $600, this is something that every road warrior can afford today, if only as a style accessory. So, the decision won't be made or inhibited by corporate IT departments.

Sure, they'll try to block connectivity to their servers on security grounds -- they always do, because they think computers are about them, not about the users' needs. Of course, the iPhone includes VPN connectivity, and most have already got their heads around that. But so many executives will have these that just like the Blackberry before it, corporate acceptance will be very fast. And, once you've adopted the iPhone as your traveling computer, how much of a jump will it be to make your next notebook/desktop for office use be a Mac?

My Prediction

As a phone, the iPhone will be exceedingly popular. If production can keep up with the demand, I believe that Apple will sell more than 2 million before year end 2007 -- if they can scale fast enough and have a new version out in time for Christmas, maybe as many as 5 million.

Steve Job's stated target is 10 million sold by end of 2008. Given that there will probably be at least 2 more versions of this product before that, I believe 10 million is a very low estimate, set so that expectations can be smashed -- again, it will depend how fast production can gear up to handle demand and support several different models, but 20 million should be easily reachable.

As additional business applications start coming online, probably early to mid-2008, expect sales to really take off. We will no longer be judging the iPhone as a phone when that happens, but as a true micro-mini sized PC which revolutionizes the entire tech industry and rejuvenates innovation throughout Silicon Valley. At that point, the iPhone will disrupt Blackberry, Nokia, Motorola, Microsoft, Samsung, and maybe even Nintendo (to name a few).

Postscript

And, what about AT&T? Well, that truly is the fly in the ointment and Steve's Achilles Heel. AT&T is brutish about customer service, slow to innovate and slow to reform. They will try to extort every possible advantage in pricing and contractual obligation that they can. AT&T knows nothing if not how to exercise a monopolistic advantage.

Moreover, AT&T lacks the broadest service coverage, and no single carrier (in the US, at least) is right for everyone. We all know that signal strength and dropped calls vary based on where you spend most of your time.

So, if you live in an AT&T dead zone, tough luck. Their EDGE network is slow, and they don't have anywhere near complete enough coverage with their 3G services (which aren't built into this version of the iPhone anyway).

It's hard to understand why Job's wouldn't let the market decide if he wasn't going to lease his own service. With a single carrier that many will be unhappy with, Apple will take the brunt of service complaints -- if I could go anywhere, I'd blame the carrier, not Apple. 

Verizon has the best coverage and fewest dropped calls. T-Mobile has the best customer service, best rates, and happiest customers.  Maybe AT&T (Cingular at the time) was the only one willing to play ball on the technology changes that Steve wanted.

Regardless, if service complaints and customer mistreatment stories start hitting the press, expect a negative backlash that could take a serious bite out of sales growth and long term success. On the other hand, wide scale Wi-Max is a technology whose time may well have come -- it would make perfect sense for independent Wi-Max providers to bathe cities in their signal, and then AT&T could become almost irrelevant in the equation (if Wi-Fi VOIP capability exists).
