Incipio known to the Zune world from the older cases for the Zune 30, released two new series of leather cases for the Zune 4&8 players. A "Wallet" model in six colors and a "Flip" model in three colors. As we can see on their site, Zune 80 accessories are coming too. Photo Gallery below..
Take a look at the photo gallery below. The cases have protection foe th screen but direct access to the Zune touch-control, so I don't think you are going to have any problems using your player when in the case.
