Proof Cases's ($30) is a polycarbonate shell with soft texture coating that keeps your iPhone scratch-free while in the case. Proof Cases also sells ($9) that can be used to increase your accuracy on your iPhone's touchscreen.

Skateboard enthusiasts, meet the ($20). This hard-plastic case is coated with real skateboard Grip tape that, combined with the case's woodgrain vinyl edge wrap, makes your iPhone resemble a miniature skateboard. SlickWraps does advise you, however, to slide the case around on furniture or other surfaces you don't mind scratching up--skateboard tape isn't exactly known for its softness, after all.
