So I've had my iPad 2 since December and use it almost everyday. I've been using the Smart cover from Apple in conjunction, and periodically I would see scratches in the back aluminum where it stands up (in typing position). I use it on my desk and move it around sometimes but the marks don't do justice to how I'm really treating my iPad. The marks started with scratches around the 4 corners and got to this. Anyone else's iPad look like this?
