Currently I'm looking at the Nokia N900 as a new phone but, I keep reading that possibly soon that a bunch of new phones are comming out and some are already out and I'm trying to debate if I should buy this phone or maybe wait for one of the newer ones and if so could you recommend one that I should look at?

The iPhone 3GS is also drawing my curiosity too but everyone has one..

The HTC HD2 is catching a eye Too

Im just looking for a phone thats in the N900, iPhone, Android OS type class..
