Is anybody using VirtualBox to run Windows on the Mac? I just installed it on my machine and I am very impressed with it. It was very easy to install and run and seems to be very light on resources. It is FREE for personal, educational and evalutation use. And althrough it is currently only beta-status I have not noticed any issues (there is a disclaimer on what is currently not fully supported - I think). I would like to see how it compares to Paralles or VMWare, but since I do not have them, maybe somebody else could do some testing against these two.
