One of the most unique cases I've come across is the Case-Mate Smart Skin. I really dig this case as it offers great protection in a compact design. It has a very cool feel to it, and the keyboard cover is a great addition. The only hard part I found was getting used to typing on the "softer" keys, but after a while I barely noticed a difference. It works surprisingly well and I really had no trouble at all typing with the case on. The trackpad obviously does sit a bit lower which felt odd at first, but after a few minutes it's not a big issue. This case gets a thumbs-up from me - if you like to go for a simple case with great protection, the Case-Mate Smart Skin is deiniftely worth a look.
