The thing most desktop-oriented criticisms of Win8 overlook is that the overwhelming majority of computers that are going to ship with Win8 installed WILL HAVE TOUCH. Comparing the experience on an existing PC and extrapolating that to how the experience will feel on devices that are sold starting in October is Apples to Oranges.
What? Why would that be? Most non-touch desktop and laptop models will continue to be non-touch but will start to come with Windows 8. These non-touch Windows devices will continue to vastly outnumber the Windows 8 tablets that are shipped, unless Surface or Windows Phone 8 devices are runaway successes beyond anybody's dreams...
Expect more laptops and notebooks to ship with touch screens.
