I accidently left my 360 on for two weeks when I went to school last year, but beyond that, I've always turned 'em off when not in use. My roommates don't...a lot of shit gets left on over night when I'm not playing, but that's because they don't give a fuck about my shit. Nice, right? Still, worst case scenario the PS3 or 360 is on like a combined 8 hours a day.
