I posted this in the VMware forum, but this info may be even more relevant here. This patent may describe the tech behind the screenshot (if it is real):

Anybody read this? Looks like transparent support of Windows apps through a VM implimentation presented through a "unified desktop interface." Sounds to me like double click an .exe file and away you go.
Presumably you'd still have to pay for/install Windows for the VM to have an OS to host, but, wow, this patent seems to describe a computer on which [literally] everything JUST WORKS. (.exe, .app, etc.)
As far as viruses go, Intel also filed a patent yesterday dealing with virus quarantine in such an environment.
