The only console of mine to ever die was the PlayStation oh and two SNES!
But I drove my SNES pretty hard as a kid I played them over 30-hrs in a row and trashed them because they would over heat. Fact isI have largely stuck to Nintendo hardware and despite you having a Wii that fried I have never had Nintendo systems just die! My GameCube was dropped from like 6-feet onto concrete and accidently fell down a flight of stairs (I brought it everywhere). The GameCube still worked perectly despite being scuffed up and battered it ran like a charm. My origional GameBoy:Pocket fell in the creek and was perfectly fine after I dried it off!
So all in all my consoles go through hell, I use them to death my 360 has frozen after I played Halo3 for two days. I have seen my Wii fall off the counter and table a couple times too! So your just having bad luck but yeah I don't play my 360 enough to kill it lol! At least not anymore!
