Speck's See Thru Hard Shell case for the iPhone 3G is one of the few cases I've seen that makes me go "Oh, interesting" instead of "bah, nonsense." Firstly because it's simple, just snapping in two polycarbonate parts around the sides and rear of the phone, with rubberized grips so it doesn't slip out of your mitts. Secondly, when you've snapped it in two, one half remains snugly on the phone while the other half acts as a stand, perfect for impromptu movie viewing. And that's just neat. It's in a variety of colors for $30. [Product page via Slipperybrick]
