yes. marketing ploy.
think of the average person who uses their pc for email, basic web surfing. you know has updates set to automatic. Machines poops they go get a new one, whats on the new one.. vista.. tada.. Now not everyone will run out an do that, but theyve got enough of a market share where they dont CARE how many user (savy users) are affected. That doesnt matter, what matters is that they just got some new folks moved to vista.
Never run any update automatically. Yes, it takes time to read the specs etc, but read 'em before you install
Keeping an eye on things via network security focus helps too
