@DCMonkey: What will happen is that Metro will be disabled on Desktops, especially for a large enterprise that are upgrading their operating system.; If a user elects that theyr want to use the touch based UI then so be it, but unless you have a touch device, Metro is useless for most people.

That message is pretty clear, so I would stop panicking, and look forward to improvements in the beta Microsoft are going to have to invest in the classic desktop, as that will take decades to wean people off, and unless they update it, people will just stay on Window 7, XP or Vista.
