I had a first gen ipod shuffle, but I've just now really joined the ipod revolution with my new 2GB nano. It came with some sort of dock, but I have no idea how to use it? What is it? It's made in such a way that you can't stand the nano up with the cord in it. What good is that? I thought maybe the clips on the bottom were for winding the wire around, or clipping it to something, but it seems I'm wrong. This dock came in the standard package bought from the Apple Store.
