They are totally different, it depends what do you need, all-in-one Internet tablet, or a smart-phone. Spec wise iPhone is better. I prefer my N900 over the iPhone because of the hardware keyboard,and free Skype video calls.(Skype > FaceTime) if you don't need that you should get iPhone NOW, or wait for some Meego device. P.S. The DroidX is cool IMHO, not too pocketable, but i love big, hi-res capacitive screen.
