Tune Belt Open View Armband Carrier for 1G & 2G iPod nano and flash Zune (4/8GB)
I purchased the iPod nano armband carrier to use while working out.  However, I have yet to use it. It is hard to slide the iPod into the carrier, and even harder to get it back out.  Additionally, it is hard to turn the click wheel once in the carrier.  I suppose the snug fit is good for working out, however, it is just too much trouble afterwards.
