Whilst the seemingly 'integrated' applications is cool (similar to Parallels on the Mac), being able to close down the actual desktop environment visually, is it not still running in the background, a bit of a resource hog me thinks? - depending on what you are virtualising mind you! I just don't see any massive advantages of this over standard Virtual PC 2007 XP virtualisation. I'd have preferred to have seen a variety of operating systems to choose from i.e. Win 98 - 2000 in addition to XP and some actual improvements upon the way that old software is handled!
