If you want protection and don't mind bulk, the Kraken from AMS is the best case I could find. I've had mine for about two weeks, and love it. To make it work with the extended battery, you have to take your stock battery case and cut out the section where the battery fits (There are indentations to follow, it's quite easy with a sharp razor). Then you fit the case over the extended battery, and cut out a square in the silicone so the extended batter fits through without creating a hump. Then install the hard plastic outer, and you have a perfect case. It has rubber covers over all the ports, keeping pocket filth out of them (I ruined my headphone jack on my last phone by pushing gunk in). The thick silicone should act as a great shock absorber, and the buttons are much easier to locate/push now. The case is solid and well built, and surprisingly enough is completely unnoticeable in my pocket (And I'm only 5'3, it should look like I have a bible in my pocket. The kickstand is excellent as well.
