I guess as long as the overheating doesnt become too much of a problem I will be ok with it. I mean my x360 gets so damn hot sometimes I wonder why the disc doesnt just melt into the tray, but I have had my 360 for a year and have yet to have a problem with it, I guess Im just one of the lucky ones as some people ave reported having to return theirs 4 times.
Except for that time when all your save games got deleted

I think people who get original release consoles will have trouble with it and have to get it replaced. This seems to be a pretty common thing now :-/
