I love mine, but the new software has a couple annoying bugs:
1. Any items missing metadata in the "album artist, artist, album name, or track number" fields will sync continuously making duplicates on the Zune. Use mediamonkey or similar clean up your metadata or prepare for frustration.
2. All the documentation you get with the Zune 80 says to hold the play button down to shut it off. What this does is put in in a hibernate mode that still drains the battery slightly, but allows you to instantly resume. If you turn off your unit in this manner at night you will wake to a half dead battery. I suspect there is a bug in the firmware, but luckily there is a workaround in that if you hold the back button and down on the dpad the unit will fully shut down. The only thing difficult about this feature is that it is completely undocumented.
These 2 problems aside< I love the unit and find having it on a dock with wireless sync actually is useful. The dock has both composite and progressive output, and the zune 80 can hold full DVD resolution. The actual interface is great and the touch control on the squircle works better than you might think. She will need a software update or two to work the kinks out, but all in all this is a wonderful media player.
