Four of my machines (including my laptop) are Vista 64 ready.
I'm considering upgrading the laptop to Vista Media Center. For my job I'll have to know about Vista, and that means some hands-on diving in. The lack of OpenGL support is putting me off, however.
My fastest desktop runs XP 64 bit. Fast, stable. Won't upgrade.
My other desktop runs XP 32 bit. It's more likely that I'll upgrade to XP64 than to Vista - I don't want the graphical goodies, but I do want to use more than 2 GB per process..
The fourth one runs a Media Center 32 bit, and it runs fine. No need to upgrade.

My other two machines are 32 bit, AMD Athlon based. Both run 2003 Server. They have hever been crashed or compromised. Won't upgrade.

The pen is mightier than the sword. But if you literally want to have some impact, use a typewriter
