Joe,
I run all 3 systems through my stereo receiver for the improved sound & switching capabilities.I like PS2 for the larger selection of games,XBox for the "XBox only" games (mostly Oddworld) & better DVD remote,& I like the "Cube" because I'm a Super Monkeyball junkie...I know,It's a kids game but since I'm a 572 mo. old kid anyway, it works out.I also have an adapter for the "Cube" that allows me to play the Nintendo handheld games on the TV.
Of the 3, PS2 gets the most use since they finally got around to releasing GT4!
