In theory, the n800 should offer a very good video experience. The processor has a hardware video decoder capable of vga @ 30 fps. This may be eventually supported since the users manual claims vga resolution. I sure hope this will be supported soon. At present, video playback on the n800 is very poor. IMHO the latest mplayer on the 770 is better either the nokia media player or mplayer on the n800.

Don't buy the n800 now for features it MIGHT have in the future. You could be stuck with a device for browsing the web
