I'm happy with at least the general video playback on my N800. Yes, it's not 24-bit color, but the screen is bigger and brighter than other comparable players. I wish it could player faster/higher-res files and also had video-out. But, it has relatively nicer stereo speakers and a built-in stand which makes it more like a little-TV set. The size/screen/form-fit/expandability is a pretty nice compromise for pocket video.

As I wrote before regarding audio, I still prefer a physical / tactile wheel over a touch screen anyday. And none of the media software, so far, is as versatile for playback. But the N800's sound w/ good headphones is pretty decent.
