Beginning with my iPod Classic 5G, I've been a long time fan of Bodyguardz. They don't really protect from drops plus they're a pain to put on "just right" until you get use to'em but I wouldn't use any other case. The best part is the security you get when holding any of your iPods/iPhone. It's a perfect case for those that don't want a case

Tip: if you're getting one for your iPod Touch 2G, line up where the USB connector goes first (bottom to top).
PS: I posted a link to the bodyguardz website but I guess my post count is subpar. Hmmm....what other topics do I wanna talk about....
