Adding to the last one, it occasionally flips out, refuses to play with you, and starts screwing things up for no apparent reason.

Not sure if I get the "on at all hours" thing for the 360. I'm looking at mine right now, collecting dust as the expensive paperweight it is, and it's pretty off.

And heavy breathing for the PS3? Mines awful quiet. It's my 360 that sounds like the mad lovechild of a lawnmower and paper shredder.
