I have an 80 gig Zune that I got around Christmas time. It recently had a fall off of a shelf, but it may just be a coincidence. It only seems to boot up when it gets plugged in or reset, but it only gets so far. The Zune loading bar loads up, and then it sort of wipes away vertically and all that is left is a backlit blank black screen. I am really hoping that the fall is just a coincidence. It doesn't seem like the force of the fall would really break it.
