Microsoft re-imagines Internet Explorer 10 as an app in Windows 8
Metro style Internet Explorer 10 on Windows 8 supports touch panning and pinching to zoom. Pages are fast and fluid like the rest of the system because the HTML5 engine takes advantage of full hardware acceleration. You can see this in the scrolling and panning performance.
There’s only one browsing engine, which you can use with two different “skins.” Over time, the Metro style experience will serve more and more mainstream browsing scenarios, even as the desktop browser continues to play a key role in many people’s lives. You can set your default to either style, seamlessly switch between them, or use any other browser you choose on Windows 8.
