iSkin Aura

I liked iSkin's Aura, which is also available for the iPhone 4/4S and other smartphones. With its two-tone aluminum back shield, it's certainly a sleek, eye-catching case (it comes in three color combos) and has a slim profile. Its only downside is its relatively high price.

Price: $35
