"snapshots can be easily taken and whole images or just recent changes uploaded to the network."
Well I suppose it depends whether "bare metal" means "just the BIOS". "Just the BIOS" can't take snapshots or do restores, which of course is why "bare metal" usually doesn't have the same meaning here as it does elsewhere. Here, maybe it means a minimal Linux. But hey, IT trendsetters (ie marketing people) have never misled us before, surely they wouldn't do it now, would they?
"Should the PC be left behind, users may be able to log onto a different PC and have the image of their OS loaded onto a server and run via a thin client application - giving them their own personal PC served over the Internet."
If I want thin client computing (and trust me, I do understand the reasons why some people might), wtf do I need a virtualisation-ready desktop system with a bare metal hypervisor? What does that give me that Citrix or LTSP or whatever doesn't already give me (other than a big bill from VMware, of course)?
