Just a quick, but surprising tidbit of non-IDF 2011 news — Microsoft announced at the BUILD conference, and reiterated in a post on their Building Windows 8 blog, that the Metro style browser in Windows 8 will rely on HTML5 as much as possible to deliver a “touch-first”, plug-in free experience. Specifically:
For the web to move forward and for consumers to get the most out of touch-first browsing, the Metro style browser in Windows 8 is as HTML5-only as possible, and plug-in free. The experience that plug-ins provide today is not a good match with Metro style browsing and the modern HTML5 web.
This doesn’t mean that Flash and Silverlight are completely out of the picture, though. When browsing in the desktop version of IE 10, the browser will support plug-ins. Additionally, if a user is surfing a site that requires plug-ins, there’s an option to see the page using “desktop view” to accomplish the same thing. So while it’s not a final blow to Flash, Silverlight, and other plug-ins, if the Metro UI is used as much as Microsoft intends, many users will use the Metro version of IE 10 the majority of the time, making Flash and other plug-ins lose mindshare and importance.
