As soon as I opened the box on my 3G iPod, I put it in an iSkin, and it's still in mint condition. The skin makes it a little larger, but nothing major. The iSkin is made of silicone, so it offers a little bit of drop protection, and there's a plastic bit that goes over the screen to protect it. On the version I have, there's a pretty good belt clip on the back, though it looks like it might break off if used too much. If you don't want the clip, it is removeable.
