Incase Protective Cover for iPod nano
At a Glance
Silicone skins are already about the simplest kind of case you can get for your iPod; Incase's Protective Cover for iPod nano is simple even by those regards. This piece of molded silicone wraps around your case, covering the back and outside edges. The large front opening leaves pretty much the entire face of the iPod nano visible and an opening along the bottom edge gives you access to the hold switch, dock-connector port, and headphone jack.
Although the open front means you have unrestricted access to all of the iPod's controls, from a protective standpoint, it isn't going to do much to keep your iPod safe and secure. The raised edge of silicone might provide a little shock protection if you drop your iPod on the floor, but if you're worried about sticking your iPod into your pocket or purse along with keys, change, etc., then the Protective Cover probably isn't going to allay those fears.
The silicone itself is fairly thick and durable and the back features a wavy pattern that makes it easy to grip, but that's about all that this case has going for it. The price tag is also pretty steep for a skin that leaves this much real estate unprotected; if you're in the market for a silicone case, you're probably best off looking elsewhere.
