My 360 usage isn't much different than Mark's. It is in my cabinet, but I keep the glass door open when playing.

On a related note, I just checked my email and this morning around 8:30 received the confirmation that MS had received the console. By 11:45 they'd sent another message saying that the repair is complete and that it's on its way back, along with the tracking number. Nice!!

GOW weekend ahead.
