Hey guys. This is my first post being made on my new iPad 2. With purchasing this, I also purchased a gray polyurethane smart cover. As you all know, the smart covers do not protect the back of the device. So, I was wondering if you guys knew of any back-only cases that were designed to work with a smart cover. I would prefer something that is thin (not adding too much heft or depth to the device) and not a hard case (silicon or polyurethane would do). Thank you all in advance.
