Why would a person buy a regular IPod over the IPod Nano? Is the only difference if you are going to watch videos or not? In everyones opinion, if you aren't going to use the IPod to watch videos or movies then is the Nano the way to go? I would say that I am mostly going to use my IPod for music, podcasts, and listening to audiobooks. What questions should I ask myself before I decide to go with the regular IPod or the IPod Nano? If I go with the Nano which model is the best (2GB, 4GB, 8GB, 32GB)?
