SAM I can confirm the Windows-format iPod issue - it did indeed screw up the directory structure on my windows-format iPod, and I'm looking at a restore now myself. The iPod thinks it has 0 songs, and iTunes "unexpectedly quits" whenever it's plugged in. Issue remains after the usual troubleshooting steps (reset ipod, reboot, even created a new user w/ empty itunes... nope, the ipod is confused.) Windows-format iPod users are strongly cautioned...
