The unanswered question is: Why does Microsoft continue to develop a web browser from the ground up?
Why didn't Microsoft do what Google did. Take WebKit as a base, put a Microsoft interface on top, call it Internet Explorer 10, and save tens of billions of dollars in development?
But, unfortunately, Microsoft is resting on its laurels, as it always does. Mobile is where the action is, and mobile browser usage will exceed desktop browser usage. Mobile is everything. Yet Microsoft's Windows Phone 7 still runs the old IE7 mobile browser, which, like the story said, is useless as a cloud interface.
