Great find. I have wondered why more people haven’t turned to virtual machines for another layer of security. This looks great and very easy for those people who don’t know much about computers. And for those who get called to fix things on a regular basis this might be a way to have many less support calls.

I think virtual machines haven’t taken off yet because they are still quite heavy on system resources. You probably want to have at least 2GB before running a virtual machine, otherwise the host or virtual machine will suffer in performance.
