Oh, it's tough alright -- sort of tough to get on, but at least you can be rest assured that it'll stay on and keep your new iPad 2 out of harm's way. The case also features a non-slip grip, which will keep you from dropping the iPad 2 when you're picking it up.
This Scosche form-fitting case is flexible and made of translucent rubber. The only caveat is that it covers the volume control of the iPad 2, and with its new, slanted body-type, that can make accessing the volume button difficult.
This Folio case from Scosche folds out into different orientations so that you can comfortably watch a film with the iPad 2 laying down on your knees, or prop up the device to type up an email. While it does add bulk to the iPad 2's relatively thin form-factor, it does protect the device in its entirety.
If you'd rather go with the Smart Cover for your iPad 2, but want to cover the back, Bodyguardz makes a PVC-based film that's really strong and protects from scuffs. One caveat, however: the carbon fiber skin is difficult to match up with the docking port on the bottom of the iPad 2 and the back-facing camera.
