Jack Spade InFlight Case for iPod Touch 4G
I didn't have this case for very long without breaking it - and I'm not one to fiddle with things until they break. The front half of the case is very thin, and is easily breakable. Once you put this case on, don't take it on and off multiple times, because it's guaranteed to break. This would definitely still work well, though, if you just leave the case on.
