Why do you need the iPod?

well, technically, you never "need" it, and if you already have an mp3, then there wouldn't be much use in it besides the fact that ipods are usually easily maneuverable, have more storage, and have more features, but if you don't have an mp3 then an iPod would be good for music, podcasts, tv shows, and some new features like Photography, cell phone connection, internet(including YouTube), virtual Musical Instruments, maps, and more.
