Your opinion is yours. Your experience as an enterprise IT support staff is going to be quite different than that of most small businesses. Even those who embrace the need for ongoing IT support. To be an early adapter of Vista tells me that you had a fairly robust IT department to deal with the issues that came from Vista NOT BEING READY for release, at least from the perspective of the small user.
The reason for this post was simply to inform those who might be effected by a surprise update that left them with no choice in the matter. Home or Work makes little difference if you are the one being surprised.
At home I don't mind automatic updates for minor updates. Every major OS version I've ever installed since MS Dos 3.0, I've installed manually.
