Zune Thoughts: Zune Desktop Software Update Released

If you fire up the Zune desktop software, it should detect that there's a new version of the software available for download. I did the update and it went smoothly - the download took perhaps 30 seconds, and the install took a few minutes. Unfortunately, it demands a reboot - wasn't there some initiative inside Microsoft to cut down on the number of reboots that software requires? I'm in the midst of burning a DVD with my Windows Media Center Edition 2005 machine, so I can't reboot just yet. Anyone else gotten further than me care to report in on what's new in this version? I couldn't see any notes about updates during the process.
