I'd argue the other way, but things may be different for you, depending on a lot of things. :-) I currently have 4 running virtual machines on my Macbook Pro.

I'd argue the other way, but things may be different for you, depending on a lot of things. :-) I currently have 4 running virtual machines on my Macbook Pro. Three running a pretty basic Debian install for testing (yay, Chef) and one running Ubuntu with a graphical user interface. And yet, only half of my memory is wired/active, and with expanding disk volumes, the footprint on my disk is even smaller on my memory.
