I have a 20gb ipod that i love but i mainly keep it in my car. When i go to the gym it is a real hassle carrying that thing around. So i was planning on getting the $99 shuffle just to bring to the gym. but the only thing i didnt like about the shuffle was the functionality of it. I would have to make a special mix just for working out because you cant really change to whatever ablum or song you want. Then the Nano came out. It gives me the functionality of my 20gb in a miniature size. BUT how much bigger is the nano over the shuffle. The shuffle is still $100 cheaper, and im mainly getting this just to work out. Is the nano worth it for me?
