IE9 and IE10 are focused on supporting HTML5 natively in Windows. The document discusses demos of real-world HTML5 applications running in IE9, patterns for progressing the web forward through standards support and community engagement, and emerging technologies being prototyped in the HTML5 Labs site and early previews of IE10 capabilities like CSS3 gradients and layout modes. Users are encouraged to take advantage of IE9 today, experiment with HTML5 Labs, and provide feedback on early looks at IE10.
