PowerSupport AirJacket in clear
I've had this one for about two months now, after going through a few others and after reading dozens of reviews. I'm very very pleased with it overall. Most crystal cases scratch very easily. This one doesn't. Most "clear" frosted cases stain very easily. This one doesn't stain at all, even when regularly tucked into a pouch lined with a black dyed material that absolutely demolished four other cases with black streaks within days. If you're using a printed skin (I use DecalGirl skins on all my devices), it fits fine with the rear skin applied. All buttons are accessible. It doesn't interfere with most speaker docks or any cables. And it doesn't "hide" the appearance of the device the way colored or frosted cases do.
Cons: Not a great case if you routinely change SIMs, as it has no opening for the SIM slot and it's not the quickest case to remove. Also, I bought mine through an Amazon third-party seller and got the version made for sale in Japan because it was less expensive; it came with fewer films than the US version, and there are a couple of sharp spots where the finish on the seams was less than stellar. (I've never seen anyone else comment on the finish issue, so I'm suspecting it's just this one.)
