I'm not sure if a read this right but by virtualization, Did you mean software like virtual machine. If it's the case I use it everyday. It's very usefull to me because I"M an IT consultant and it's allow me to get number of sofware and different OS on the same machine. Presently I have as base OS windows 7 . But In the virtual machine I have 2 linux (unbutu and fedora), xp pro 64, vista ultimate 64 bit, and all the software I need to work. I used that only for 6 months, I don't understand why I wait so long to use it.
In my case I do use the visualization for my windows 7 ultimate because I am running programs in XP mode..
it does come in handle for other styles of software as well. it's a good find if you have a CPu that does support
visualization and 64 bit...
