Windows OS seems to have that weird Star Trek movie curse... where one movie (in this case Windows OS) would do good, the following bad, the next good, etc.
Windows 8, IMO seems bad from a desktop viewpoint... especially since majority of the current consumers just use regular or flat monitors with no touch capability.
I doubt (though, I could be wrong since consumers are willing to purchase expensive Droid/Windows - phone/tablets) that the average consumer would willing to pay for a touch screen monitor to swipe between applications in 8.
Will gladly alt-tab or mouse over to the task bar to switch between programs that I have minimized.

Now that you heard (this case 'read'), what I thought... time to bring this in a positive light.
IMO, this might be quite a helpful for individuals with disabilities. Especially if marketed to the tablet market, the all in one Monitor/PC system, or reasonably sized touch screen monitors for desktops/laptops.
