What is the difference between the iPod shuffle and other iPods?
The iPod shuffle models are substantially different from the “full size” iPod models, as the iPod shuffle series consists of tiny MP3 players with limited capacity and no display. Instead of using a “ClickWheel” for navigation, the iPod shuffle models use a simple control pad and slider. In general, the iPod was designed to allow people to carry their entire music collection, or the vast majority of it, along with other files (including photos and video on some models), and the iPod shuffle was designed only for music use at a much lower price.
