Yea, i borrowed my buddies, it was workin just fine, he went to use it after i used it, and it doesn't start up... its recognized by the CPU and all, and i've updated the firmware on it and whatnot... hopefully the company will be nice and replace/fix it... i don't feel like shellin out the cash for it -- I'd replace it since i was the last one who used it working, even though I didn't break it
