As an AAPL supporter I really hope that they have done their homework on this. Touting it as the best iPod ever and a smartphone revolution is a big move. Cellphones are definately more mission-critical devices than DAP and PMP:s, and a poor execution and follow up will harm the companys image.

What I find most disturbing on the iPhone is:
No user replaceable battery, on a device with such a high cost, there simply is no excuse for it. On a device that have to be charged everyday this is a big drawback.

Two-year contract obligation and only one service provider. Hopefully this will elliminated when the phone hits europe.

To low capacity, although I suspect the iPhone (if it can remain a commercial success) will recieve capacity upgrades. 4 resp 8 gigs isn't a whole lot for a device that claims to be the "Best iPhone ever", especially since phones like the Nokia N95 support SDHC micro-sd cards for expansion and hotswapping.'

Only web-based 3rd party applications, this is what drives the Symbian and WM based phone community.

I think Apple is taking a risk when they put so much effort into diversifying so that they forgo their usual product cycle upgrades. Many of their big sellers have past their TBU dates with almost 2x.
