Just a point to note, since it's Beta software Microsoft don't actually have to ensure upgrade compatibility when RC1, etc and the final versions are released, so you may have to reformat again when they come out.
(Beta 2 expires in July 2007, so I'm told)

So, no, don't use it in a production / home environment. VMWare is a handy tool if you want to see how it works though.
