Offhand I'd say that all depends on if you need the features the iPhone offers. I got mine because I wanted a full-fledged iPod combined with a phone. I also find its various other smartphone functions sweet and the free applications I can get off the installer.
I wouldn't automatically recommend the iPhone to anyone who didn't display some kind of need for some of its key features to start off with. If all you're looking for is something to phone and text with, or if a function-loaded MP3 player on your phone isn't all that important I'd tell you to give the iPhone a miss.
Unless of course you really, really want it just because it's the iPhone, but in that case I think you'd already have it =D
I had a Motorola for the longest time and it always served me well. *shrug*
