Not the IE you're expecting

The Metro version of Internet Explorer 10 is remarkable for its unique interface, its fast page-load times, and its surprisingly effective security policies. It also has Do Not Track turned on by default, setting the stage for a battle between Microsoft and advertisers.

Interestingly, it's IE 10's hardware acceleration and JavaScript engine that power the smooth app transitions on the Start screen. Here, we see the app with the top-edge open tabs and bottom-edge location bar open. Usually, they remain hidden to maximize the screen for the site you're looking at.
