Interesting, but the MP3 player market seems to be somewhat of a fluke in terms of resisting commoditization. Perhaps it's due to the iTunes marketplace keeping Apple's product line superior, in which case the iPad + App Store combo could end up doing the same. Then again, the iPhone doesn't have the market share that the iPod does, and I think iPhone market share will peak and then drop as Android and other mobile handsets come online that are truly competitive.<p>On the other hand, businesses generally buy PCs because they're far cheaper, but the market for MP3 players in a business context is basically non-existent, whereas it's potentially huge for the tablet market, so that's another mark against Apple.<p>It'll be interesting to see how it all turns out.
