The biggest complaint i see about the Smart Cover is that there is no protection for the rear.
I completely agree! I want to make sure my device stays in great shape. So without buying another case or waiting forever for a good alternative to come out i went ahead and used this.
They are just little sticky rubber tabs i bought at WalMart. I would have preferred black ones to match the 3G bar but this works great!
I put them on all four corners. They were the smallest i could find. I would like to go smaller if i find some.
You can see under the whole thing. Nothing is touching to get scratched.
If you place them close enough to the edge they even protect when in "typing mode" of the SmartCover.
its great for me! maybe a bit tacky for some but i dont worry about setting my iPad down on a rough service anymore.
