Glad you have no problems, Rutra. More Vista sales stems from it being already installed on most of the new PCs. I know of people who demand Vista be taken off and XP be put on instead.

Our IT guy is not a fan of Vista and he's a Microsoft guy all the way. Corporate IT will not allow Vista to be installed. Too many problems with programs, etc., and they aren't going to upgrade computers for it as well. XP Pro is still their OS of choice.
 
The people I personally know that have Vista hate it and want to buy Macs!

From what I've read about XP Pro 64, it doesn't use as much memory as Vista. With Vue needing so much memory, I would go with XP Pro 64 before Vista. And what ever happened to holding on to old computers?  :)  Besides, I believe the original poster was doing a dual boot so they shouldn't have big problems. And XP Pro 64 costs less than Vista.
