Firstly get with the program, http://windows.microsoft.com/en-gb/windows/preview
Download the ISO, create a new virtual machine and bish bash bosh - minutes later, Windows X
(using a VMWare Fusion on my macbook pro)
It feels like Windows 7.5 (!) ;-)
File History - interesting - is this the start of TimeMachine for windows? (Perhaps not) - I will play when I attach a USB drive.
Well thats it for now, it looks good, its quick, I might just switch over as my main OS. ;-)
