Phones are the new cars

This thought actually originate from an article from "The Economist".
How much are cellphones and cars used the same way - No, I do not mean you drive a cellphone, nor make phone call through cars (even though nowadays you can do it) - what I mean is how much of a statement one can make by pulling your phone (with all the customized ring tones and etc) on a bar - isn't it the same sort of statement one would make by arriving on a specific car? For teenagers, both cars and cellphone act as symbols of independence, freedom and mobility, with unexpected social consequences.
But what does it tell us about the future of cellphones? Instead of the expected convergence, the history of the car suggests that the exact opposite may happen. More and more cellphones should look apart from each other. No one asks what the ideal shape for a car is, more and more you have developed and new niches ( SUVs, Sedan, Sport and etc ), and the same should apply to cellphones where different phones would specialized on different applications ( there always will be the RIM's Blackberry for heavy email usage, Nokia Ngage for gamming, different ones for pictures and etc ).
Within this context, small wonder then that Nokia, recruited its design chief, Frank Nuovo, from BMW.
