Well, then let's go imaginary for a moment.
If Apple were to release the "iDoitall", which'd have the form factor of a Nokia Communicator 9300 (maybe slightly wider even), a good keyboard, media playing, messaging-multitalent (3G, GSM, EGPRS/GPRS, WiFi, Bluetooth, everything) with a decent 3-5 MegaPixel camera today, I guess they'd do so because they got it right. Alas, I just don't _think_ Apple will do that. And as long as the device is something that somehow caters to a Nokia's or a SonyEricsson's needs, I guess Mac compatibility and iTunes/iMedia integration will be an afterthought. Plus: It'll be slow. Or at least JUST so imperfect that you're going to want the next version, too. :P
It's a sad thing, but none of the mobile phone makers actually want to create the 'finished' mobile phone. Unless we're talking Vertu. But they _do_ charge.
