I bought one - plus an IPad 2 to go in it the other week
Does a great job in protecting the back. Just one thing to be aware of - there is no cutout for the rear camera. Not a problem for me and it is easily removed if you want to use the camera. You can also still use Apples clip on over with it although it does restrict using that as a stand.
I also got a black sleeve case with discrete Mickey symbols. Both that and the back get a lot of comments at work!
