Ah... so much 'ate for eight...
it would be funny if the Germans find something objectionable in the next OS version (they'd be saying "nein!" to Nine)

The one problem that I see with Modern (nee Metro) is a chicken-or-egg problem. They need compelling apps to convince people to want to keep Modern around. But by removing the Modern screen, there isn't a compelling reason for developers to develop any apps for Modern. And let's not forget some of those "convertible" types, which go between tablet mode and netbook/notebook style modes -- what kind of "face" should they present? Granted one might have to start wondering if the whole "one size fits all" is a good idea or not.
