I keep hearing people say the N810 won't play video files encoded for ipod, but I am running OS2008 on my N800 (same software) and can run ipod encoded .mp4 videos using the built in media player.

In addition once mplayer arrives the video capacity of the N8x0 will be unmatched. (I hear some people have gotten mplayer to work by fooling around with libraries/dependencies, but it is not 100% as of now)
