These things are seriously disrupting Apple. Iphones and Ipads were the rage until about a year ago, but then companies started cranking out comparable devices that retail for 1/4 the cost, and they created an entirely new market (e.g. people who can afford to spend $100 on a phone, but not $800), which has over 1 billion participants.

Unless Apple comes out with another game changing product, I dare say they are toast (though, I must admit that they are sitting upon a ton of cash).

I recently read the Innovator's Dilemma, which was penned well in advance of the iPhone craze, but Apple could easily provide yet another case study for the author (i.e. strive for high volumes and low margins in markets that don't yet exist, and you can overtake the big boys).

ETA: I know I'm getting way off topic, to the extent that my post probably belongs in OMNI, but can you guys think of any companies that are not disruptable? My answer is Google only, but even its day will come (i.e. at some point, it will turn into an IBM). My (distant) second answer would be FedEx because this 3D printing thing is bound to make them less and less relevant. I can almost guarantee that our beloved FT will be disrupted within the next 5 years because technology is far better now than it was in 1999, and our IB people are still wedded to their old ways; they have created an awesome community (big check mark for this), but half of the content is worthless, and it's not really curated, apart from the stickies that non-paid blokes like us create (e.g. I showed my biz partner "One day in Shanghai" this morning, and his reaction was, "you guys are pitiful").
