Well, that isn't quite true. I didn't have music, but I had pictures, which was weird. Yesterday I downloaded new iPod software and didn't think to check to see if my songs were still there. Then I got to work today and discovered it empty!! AGGGH!
Thankfully, I got it fixed, although I'm not exactly sure how. ITunes said my iPod had stuff on it, however I couldn't access it. After downloading the latest iTunes update, and syncing it a couple of times, it looks like everything is fine now.
I'm very amazed that I got through the afternoon at work without my iPod.
