I have no clue. From what I know, he's not banned (if he's reading this, I'm going to pound it in that he's pushing it to the limit, and his safety is not guaranteed.)
my friend has an xbox. halo's pretty fun. it worked perfectly for him because he just so happened to need another DVD drive. (He had a portable one before.)
if this thread was made back in, say, October, I'd be all for the 360. and I'm still considering it when I upgrade to vista. but the big decider will be if GoW will be for vista. Rumors say it might, Microsoft hasn't said much, and I'm sure it would be a nice selling point. it'd be awesome with the upcoming vista+xbox live hookup.
If I had wads of cash to blow, I'd get a PS3, but IMO, that extra $200 can go to games, or even a nice RAM upgrade.
The Wii looks awesome, and I'd look into it, even if just for the virtual console and being able to flail my arms wildly and actually achieve something.
for handhelds, a PSP isn't on m y list, as I've heard some bad things about the games for it (mostly that they're like playstation ones only with dumber controls and a smaller screen). a GBA is now out of the question, because the DS does all GBA games, and if I want a gameboy I'd probably just go buy one off my friend. a DS would be nice, even if only for NSMB. heck, that's all I used to play on the SNES. plus it's GBA compatibility is nice. I could play TLoZ:aLttP the way it's supposed to, and without cheats (read: I could remain stuck at the desert palace)
