I have an Innocase II and I replaced it with the Otterbox Commuter.
The Innocase is a little too thin and the Otterbox is perefect IMO.
I second the Otterbox Commuter Case. I have it as well and it's awesome and well worth the money spent! Very low profile, easy to install, and offers a lot of protection. QWERTY buttons on the edge are also easily accessible!
