I'm glad you just learned "FUD" and are putting it to use.
I'm kind of getting the impression that you haven't used Win8 much yet? If you have, you'll notice that many of the important apps that most people use daily (Mail, Music, Weather, Store, Calendar, etc) are all Metro, full-screen apps that can't be used in desktop view. The only items that you can open on the desktop are apps you install that don't yet have a Metro version.
It is an obvious shift toward a Metro-only experience (ala iOS). The only reason they're allowing you to use the desktop is to ensure temporary backwards compatibility with apps that haven't made the leap to full-screen (I'm sure MS views this as a necessary evil. Having two design/workflow paradigms is a painful user experience, but they can't afford to completely do away with the desktop all at once and live to tell about it. To the end-user, it is like running two OSs in parallel). Trust me, they will. When they do, you'll be stuck with Metro for good.
Just wait until you use Win8 as your daily driver and then post back about how much simpler the workflow is than Win7. It isn't even close.
