Query: Pretty good picture quality

Been using this with Yahoo Messenger and it works pretty well. I haven't figured out how to use face-tracking with Yahoo, though. Picture quality is a LOT better than some cheap webcams that you can buy -- so spend a couple more bucks, it's worth it. My only REAL problem is it wouldn't work with Windows 2000. (What do you expect? It's a Microsoft product) I still have a decent desktop with W2k so it's a bummer.
