I used to use Skinomi skins but now they have too many little pieces on the sides and are harder to put on the right way so I'm looking for alternatives. I strongly dislike cases that add any significant bulk to the iPad. My main reason for putting anything on is not protection but better grip (I find the brushed aluminum ultra slippery), that's why I liked the skins. I wouldn't mind a little extra lip but don't see any reason to protect the back of the iPad since its sturdy aluminum. A bumper case would be an option if it existed, as it would give me better grip like the skin did. Or one of these ultra thin 0.3mm cases they make for iPhones. Anyway, suggestions welcome.
