Do I need to have an iPod or a Mac to use iTunesU?
No. The iTunes audio will be in mp3 format, and will be compatible with any mp3 player. In fact, you do not have to own an mp3 player at all. Any course material can also be listened to or viewed from a PC or a Mac. MP3 players simply provide a way to leave the computer behind and make the iTunesU content portable.
