The MP3 player marketplace, when apple entered it and gained its dominant market share, is entirely different from the cell phone marketplace now. Apple is entering an already well developed cell phone marketplace. I don' think the same could be said about the MP3 player marketplace when Apple entered.

I have to give Apple credit for making a sleek and highly marketable device, allowing them to take market share in MP3 players while competitors had their thumbs up their arse. Competitors in MP3 players still don't seem to get it. But people are already onto that sales angle in phones (see RAZR, SLVR, Q, etc).
