The interface of Zune player

Buttons - A menu button on the left of the circle, scroll buttons in the circle, play/pause button at the right of the circle.

A hold switch, just like iPod's on the unit’s top is located near the headphone port.
By pressing up and down on the wheel, you can scroll up and down through menus. When you hold the scroll button to check the song list, the screen superimposes the current alphabet letter over the right side of the song list so that you can know how far you have scrolled.

The screen - bigger but similar to iPod's menu hierarchy. Zune's album art is larger and more detailed than the iPod’s largest size.

FM Radio - North American, European, and Japanese frequencies.

Wi-Fi - ability to spool Zune music to a Wi-Fi-enabled Xbox 360, but you will need a $100 wireless adapter.

Size - bigger than iPod.
