I use my Ipod Nano when I run. I love it. I have a sleeve that it fits into and has a clip to clip to my shorts. It came with an elastic thing so that you can put it on your arm, but I found that very uncomfortable and it seemed to slide down. I have never had a problem with it skipping, but I have noticed that if you want to advance to the next song, it doesn't tend to want to when I am running. I have to be walking.
