Stick to your mainstream
I'm perfectly happy with my SE P1i (WiFi, Opera broswer, push mail, touch screen, 3.2 Mp camera & 3rd party apps in a package that fits neatly in the pocket).
Cost me a lot less then the mainstream "smartphones" phones which all get regularly reviewed as the "top selling" phones, plus the RIM and N95 owners I work with keep asking where I got mine from (owners because very few ever seem to actually use more than 30% of the functionality).
That and mine never gets picked up by accident from the office desk because "it looks just like my one, sorry".
Still, I always wished I could call my mates from my walkman, so good luck to the iphone.
