/me considers getting an XBox... always wanted to play Halo.

Don't. Halo on the XBox is not worth it. It's so scaled back from what was hyped, it's unbeleavable. Wait for the PC version next year, Gearbox might redeem it a smidge, and at least give you proper controls.

And yes, XBox has been HDTV since day one. It varries by game on what it supports (the higher the resolution, the worse the preformance, same as the PC). 480p seems to be the minimum, but unfortunatly I can't find a comprehensive database somewhere listing every game and what it supports. After seeing my Dreamcast on VGA (480P basicially), the difference is amazing even at that low of a resolution.
