I use Vista 64 on my workstation w/ 12GB of RAM and it has been the most stable system I have ever run. I do use VMWare on it and, in fact, run Win7 64 bit in a VM with VERY respectable "Windows Experience" numbers. In the mid 7's across the board. It is nice to have a Win98SE, XP Pro, and Win7 64 VMs suspended and ready to run in seconds so I am looking at EXACTLY the same OS a customer is looking at. I don't get all the foot dragging and complaining about something they have no real experience in. Like the "I skipped over Vista because....." how would they know that if they skipped over it? From the Apple ads on TV? I certainly like Vista better than XP.
