Fantastic bit of kit. All my music now on one device and I bring it everywhere. Play it in my car, out walking etc, etc.
I have the Windows version and it works flawlessly. BUT only because I never used the software (Musicmatch) that comes with it! I took advice and use that as a coaster!
I use Cedex for ripping, ID3-Taggit for tagging the MP3 files and Ephod for transferring the music from PC to iPod. trust me it's simple, if I can do it.......
They are all freeware programs and you'll download them in a few minutes.
Make sure you have firewire. Battery life is about 10 hours.
I'm so impressed that I think I'll be making the switch to an iMac and powerbook very soon! (This is part of Job's strategy I believe by making it available for Windows)
