For the cassette-craving hipster in you that still requires 30,000 songs at their disposal, fredflare.com shows off the "rock it!" iPod case. Also available in a similarly retro boombox pattern, the case features a suede interior and retails for $36. Plenty of double-takes are guaranteed, but will they be from people who appreciate your ironic nod to the past or people who think you look like a douche? Let the asymmetry of your hairstyle be your guide.
