Microsoft Internet Explorer 10.0 Platform Preview 2 (2.10.8103.0)

Updated for those who care....

IE10 Platform Preview 2, available for download today is the first step in delivering the next wave of progress in native HTML5 support. Web sites and HTML5 run best when they run natively, on a browser optimized for the operating system on your device.

We built IE9 from the ground up for HTML5 and for Windows to deliver the most native HTML5 experience and the best Web experience on Windows. IE10 continues on IE9’s path, directly using what Windows provides and avoiding abstractions, layers, and libraries that slow down your site and your experience:

The only native experience of the Web and HTML5 today is on Windows 7 with IE9. IE9’s approach to taking advantage of what the operating system offers – from the native graphics stack to jump lists in the shell – maximizes performance, usability, and reliability. We released a fast, clean, trusted, and interoperable IE9 globally for consumers and businesses four weeks ago with the goal of delivering the best experience of HTML5. The best HTML5 is native to the operating system, so Web sites have the fewest translation layers to pass through. The best HTML5 enables sites to use the same markup – the same HTML, CSS, and script – across browsers. The best HTML5 respects developers’ time and enables same markup by treating site-ready HTML5 differently from unstable technologies.
