apparantly, the SoC's of the N900 and the iPhone 3GS are very much alike - but there might be some major differences with the DSP's.

iPhone 3GS's SoC: http://www.anandtech.com/show/2782/2
N900's SoC OMAP3430: http://en.wikipedia.org/wiki/Texas_I...nts_OMAP#OMAP3
N900's SoC (link 2): http://focus.ti.com/general/docs/wtb...P3430Processor

the N900 should still be able to handle 720p by using a lightweight encoder (=probably not h.264).

Samsung i8910 handles 720p with the exact same SoC as the N900.


the camera sensor should not be of concern as the N900's sensor handles 5 MP - more than enough for 720p
