I currently have the 4GB 3rd generation nano. It is nice and small but I work out regularly, atleast 6 times a week. I like to watch movies and tv shows while I work out. The 4 GB doesn't hold a lot of videos. I have a voyager so I know how to navigate a touch screen and enjoy the features but I also use my ipod in my car and want something quick and easy. I only have around 300 songs but just would like to know I have the space. What do you recommend?
