I really want an Ipod, but I cannot decided for anything. There are two reasons why I want an Ipod, to transfer files, and to have a music player I can run and exercise with. I have a lot of data that I need to transfer around, and I do not think that a 4gig Ipod will be enough for me. I COULD manage it, but it would be tight. With a mini though I could run, and take it to the gym- and work out without worrying about it. I really cannot exercise without music, cause its unbearably boring to do so. On the otherhand, a 20 gig ipod would give me plenty of space to transfer files, and listen to music, but could i exercise comfortably with it? I looked into other music players that are made to exercise with but they dont have the space, and they arent apple. hehe i want to stick to the apple Ipod so either the 20 and a mini silver are my options. So basically it somes down to: Can you exercise with a 20 gig Ipod? Comfortably?
