LMAO!! I have told clients under no uncertain terms that if they upgrade to Vista before my OK, that they're looking for a new tech. One of them didn't believe me and did it. They're looking for a new tech. SP1 minimum is what I tell them.
That seems a good practice for Bikes and cars too.
We have been running Vista on a couple of machines since the beta came out, year and a half ago, also office 2007.
I have no problem with Vista, as long as you have 2 gig of ram or more. We have around 800 computers at our school, so buying ram and up grading to vista is not going to happen, but as we replace units, we will go to Vista. We had to load Office 2007 on 2 labs at the High School, because that is what the new text books have.
