The main issue with that is MS made a million different versions of Vista and some of them had significantly higher requirements than others. So you had OEMs selling machines that were ‘Vista Ready’ in the lead up to launch but they barely made the requirements for the basic version. Then you had people going to Best Buy and getting the premium version and having a horrible experience.

I had Vista on my MacBook Pro and it was a a solid OS, especially if you needed 64-bit support. In fact the Pro was PC Magazine’s #1 pick for Vista machines which caused quite a stir at the time when Bootcamp was still new.
