The entirely new Internet Explorer 10 is a huge part of the new Windows 8 OS.
IE10 is the Windows 8 browser. It is fast and fluid when it comes to performance. Most importantly, IE10 is arguably the first browser designed for touch.
The new browser comes with an entirely new modern touch-first UI, while the underlying platform technology in IE10 around touch allows developers to create new experiences.
New features in Internet Explorer 10 include:
Full-Screen Browsing: IE10 appears only when you need it, and quietly gets out of the way when you don't.
Flip Ahead: With Flip Ahead, IE10 makes clicking "Next" obsolete. A simple "swipe" gesture allows you to advance to the next page, or article, or image on sites with "Flip Ahead" functionality.
Pinning: IE10 allows you to pin your favorite sites to the Start screen just like apps. Simply tapping the "Pin to Start" button in the navigation bar will create a tile on the Start screen so you can put your favorite sites right alongside your applications in a display that will truly make "Start" your home.
Snapping: IE10 makes multi-tasking easy by allowing you to simply "snap" IE10 to one side of the screen, while having another application - ch as Mail, Xbox Music or Microsoft Office ? open on the other side.
