Yep kids have had them for years and no problems, I have the feeling it's probably the people that sit in front of them for 12 hours at a time that begger them
I've had my 80gig PS3 since they launched the 80g model. Countless hours on it, no problems. Fan runs alot, but it's in a fairly well ventilated area.
No xbox360, but i still have my original Xbox. My son plays it often. You have to tap it to get it to open.
