I'm currently a Zune 80 owner and I _love_ it. The player is solidly built and the newer releases of the desktop software have been fabulous.
However, I'm migrating over to a 100% Linux desktop in order to take advantage of a more stable programming environment.
Thus, I need to change players from the Zune to something that is compatible with Linux.
Here's what I'm looking for: video, picture, and MP3 playback, 60-80GB of space. If it plays ogg, nice -- but, it must play back MP3. I _DO NOT_ want an iPod.
