Beta 2 of Vista and Office 2007 is working on my desktop machine. It took me a lot of time to get Virtual Server working again. But I did it. and I am beginning to think about migrating from XP to Vista on my production laptop.
(After I created a ghost image of the current install that is stable.)
The beta 2 does take less of my memory than the previous builds. (even though it still takes 600 MB of it, the last build took almost 1 GB) so I can use Virtual Server for demo’s.
