The difference between iPHONE 4.0 and N900 is that in iPHONE, everything is polished and bug FREE. Nokia N900 rely on community to help develope everything it seems...from mms to get focus while recording a video....to setting up the front cam to make it work. iPHONE 4.0 have all that straighting out...that is a HUGE difference. And no such thing as battery drain (hello Nokia ?). iPHONE 4.0 is just less headache....and it's ONLY $200 BUCK...
