Microsoft is sure trying to piss on it's desktop users in order to gain tablet and smartphone users. The really mouse hostile metro UI is not that well thought IMO, example if you're on IE10 one metro and try to install silverlight it will go back to legacy UI since Metro wont support plugins (yes not even adblock) then after you've finished browsing in the page you needed the plugin it will return to metro again. Not what I would call a plesant experience.
