If you thought Windows Genuine Advantage was a treat, wait till you see Vista's antipiracy technology. Users who install Vista will have 30 days to validate the product; OEM installs will come pre-validated. (So much for encouraging people to buy new hardware now and upgrade later.)
If the validation fails, Vista will shut down your browser after an hour, prevent Windows Defender from running, and nag you 24/7 until you validate. Of course, it's possible the whole thing will work flawlessly. Wait, I think I just saw a pig fly by my window. Or maybe it was another Microsoft product manager completing his exit interview.
