The only ones that broke "naturally" were my 360 and PS2.
Unnaturally:
I pawned my PS3 at a pawn shop for some gas money(I picked up a little later on payday) and it was broken! They didn't even take responsibility for it, they said it was already broken when I brought it in

.....And they try everything out to see if it works(so they don't get ripped)before they take anything in.
The first XBOX was trashed to hell in a party

...people poured beer on it and stomped on it. Someone wanted to set fire to it but the beer prevented that.
My 64 disappeared...really, it just up and disappeared...my house was locked and everything and nothing else was missing.
My GF's PSP just stopped playing the UMD's one day(it was loading up a game), like the UMD would physically not move anymore. EBgames said the warranty covered it, but as soon as it came back they wanted me to pay almost full price for a refurbished...What the hell happened to the warranty? isn't that the whole point of a warranty? So you don't have to pay for repairs when it breaks.
