So yesterday I was playing around with my APAD, and it started getting hotter than usual and all of the sudden it had turned off. Has there been any known instance of one of these overheating? I've had this since Christmas and it's worked pretty good (besides the touchscreen problems and USB problems and such). And unfortunately it's not working at all...Won't even turn on or anything. I'm just wondering if there have been any other instances of this or if it's just me.
