I'm a huge klutz. I fully admit it, and I prepare for the inevitable dropping of my phone. To this end, I got myself an OtterBox. It has worked very well; since I've had it, I've dropped my 3G on hard surfaces nearly a dozen times with no damage. However, the case is wearing out, evidence of my abuse, and I'm looking for a new one. I'm interested in getting one of those cases with a built-in battery to give me additional battery time. I certainly use the phone enough to justify the expense, but browsing around, I don't see such a case that offers nearly the protection that my OtterBox has. They all appear to have hard plastic shells and none of them seem to offer any form of protection to the face of the device. So am I missing anything? Is there a case out there with a built-in battery suitable for a super-klutz such as myself? Thanks!
