I was actually discussing this with Boe yesterday on MSN, apparently it's more then a simple "fault" I've heard the consoles are making people literally ill.
And yes, I've had nothing but problems with mine from day one, things from putting in a brandnew game and getting the error message "To play this game, Please put it in an Xbox 360 console" to the current problem of being forced to use a knife to open the tray.
Fuck Microsoft, I'm getting a Wii.
