I am looking for a well made TPU cover to protect the back of my new ipad with the smart cover. I have heard that TPU provides some drop protection (not a lot) and is less likely to crack or fall apart than something like the belkin snap shield. I am not looking to lock the smart cover on (doesn't that kind of defeat the purpose of the smart cover?) but I wouldn't say no to a good magnet to hold the smart cover to the back. I have a cheap one for the ipad 2 to carry me over but it gets underneath my screen cover and causes air bubbles on the side. Any ideas?
