I ran a few betas and the final, and wasn't impressed. It can slow systems down about 10% compaired to 98 on the same system. Many beta testers were calling it Win 98 Third Edition. Personally, it's not worth the upgrade. If it comes with a new PC, then I have no problem with it (except for the fact that I use and love 2000 for all the time I run Windows).

The biggest feature I can think of in it that may be useful is System Restore, but it won't pull you out of all mistakes. GoBack from WildFile (err, Adaptec now) can allow recovery from everything including a format c:, and offers many more features like file revision retrieval, and more.
