I got the Apple iPod Nano Tubes. They are actually pretty nice if you're looking for a skin-tight type case. They don't add too much bulk to it, and they come in 5 colors. They even cover the scroll wheel, which is pretty cool, and that cuts down on the oversensitive scrolling some have reported. The only down side is the lack of screen protection, but I got some clear cling-on camera screen protector sheets and that works pretty well to stop scratches on the screen. I'm a big fan on the iSkins, but their Nano skin is still not released, so I'm still waiting for that to see what that's like. They're nice because they have little hard plastic screen protectors with those.
