MS will never back off Metro. It really doesn't give a shit about what it's customers want.
It will just put an EOL on Windows 7, and once it passes,there won't be any choice.
It has that kind of power, which is sad.
They simply aren't going to put back in code they intentionally ripped out.
if that happens and they are that un-responsive I think we'll see Linux start to gain legs again, like it did when Vista was the MS flagship.
