Don't rear projection TV's need big rooms to work right? Will my XBOX work with it?
Yes, you do need to be a "reasonable" distance away from the TV for an optimum viewing experience.
I sit 8' away (from front of screen to middle of couch cushion) from my 57" widescreen HDTV - and that's perfect for me. Any closer would make me sick when showing movies with lots of motion, and any further away would reduce the screen filling up my field of vision (which I like, as it gives a definite movie theatre feel).
If you can't sit around 6 - 8' away, smaller (40" or less) is probably better.
Newer projection TVs work just fine (in fact, great) with the Xbox. New projection/DLP TVs have a much reduced rate of burn-in, and the newer systems (Xbox, PS2, GCN) have games that also reduce the chances for this. As long as you don't leave the games on all the time (and turn off the TV when you pause), you will
never ever get burn-in (a friend who's been playing loads of games, including the older Dreamcast, on his older projection TV for more than 6 years has no burn-in whatsoever).
In fact, the Xbox is designed for high-def TVs, since most of the games are progessive-scan compatible (usually 480p, but at least one game is 720p). Pretty darn cool.
