I understand that users who don't like change (and I would probably count myself among them) are going to be uncomfortable initially. But, just like GUI was in its day, this is an important change and to not be moving forward at this point is very much moving backward.
If users simply had the ability to turn it off it wouldn't be a very effective shift, would it? People are naturally resistant to change and love to stick with what they know. I can probably count on one hand the amount of bold design choices, that turned out to be effective in the end, which were initially berated by the user base (leers at Facebook).
True that it is a paradigm shift, however, I liken it to trying to blur the lines between flying a plane and driving a car.
In prepration for the day when we will all be driving flying cars all car manufacturers have agreed to release cars without the standard user interface constructs (steering wheel, brake pedal, accelerator, and gear shifter). Instead you will use a standard airplane yoke controller for steering with height control surfaces to be added at a later date. Your acceleration and deceleration will be controlled by a seperate sidestick control.
Plain and simple, the Windows 8 interface is more for a niche crowd and does not take user productivity and familiarity with a product seriously.
