IE10 Platform Preview 1 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. Microsoft 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.
Native HTML5 and Real-world sites
Native HTML5 support in Windows with IE9 makes a huge difference in what sites can do. Microsoft demonstrated real-world sites from the development community that a year ago would have been possible only with a plug-in or application. These sites are live now and show that the technologies as implemented in IE9 are production-ready for consumers and businesses.
IE10 continues several patterns from IE9. In addition to the Platform Preview available for developers to download at www.ietestdrive.com, Microsoft have posted new test drives and over 500 new tests they have submitted to the standards bodies. IE’s approach to emerging standards results in less churn and more progress for developers. IE10 builds on full hardware acceleration and continues our focus on site-ready Web-standards. This combination enables developers to deliver the best performance for their customers on Windows while using the same, Web-standard markup across browsers.
