Did my research. From what I can tell the duo iSkin seems to be the best option for my iPod nano's case. It comes with a removable belt clip and a hard-plastic screen cover.

Checked the reviews, mostly 5 stars.
The other thing I wanted to go with was the Incase Neoprene Sleeve, but the plastics sticks to the screen and scratches it. Not everybody expressed this being a problem, but I think the humid air in Georgia would make it a problem for me. ( I saw this one at Target, it has a flexible plastic covering).
The nano tubes are neat, but they provide no screen protection... plus I don't want to have to buy 5, that's a waste.
So, I think either the iSkin or a nice, expensive leather pouch would be great. Just kidding about the leather.
Which color iSkin is your favorite? I like Purple Haze.
I think I made a post about my iSkin. It lasted about 11 months before it developed a tear on the corner of the screen area, and the dock connector protecter ripped off. So I got my money's worth. The only problem with the iSkins is that it makes it REALLY difficult to take your kPod out of your kPocket. I had a friend that never had any protection for her Nano, and withen a week it was scratched everywhere, so make sure you use that screen protection. If your kSkin starts to attract a lot of dust and hair give it a bath in warm, soapy water. The Nano's are way cool, nice job!
