Folks have warmed up to the 360 perdy well from what I hear. Word originally went from it supposedly being crap and scratching games and other such things to being one of the best designed systems in a while.
I've still never even played one, but I heard that even while playing games, you can bring up the menu/blade system to do whatevers. That's prolly handy.
That said, I still wouldn't spend $400 for a video game system.
