RhinoSkin now offers an aluminum hardcase for Apple's third-generation iPod nano. It costs $24.95.
Designed to fit the contours of the redesigned 3G nano, the case features a clear scratch resistant and shatterproof front mated to an aluminum back. Soft grip sides keep the case firmly in your hands, and the clear front lets the iPod's color come through. A lanyard is also included so you can wear the iPod nano around your neck.
