this has been clear for a while. Ballmer said as much at a recent financial analysts' meeting: <a href="http://decav.com/blogs/andre/archive/2010/10/27/ballmer-microsoft-s-strategic-ria-platform-is-html5.aspx" rel="nofollow">http://decav.com/blogs/andre/archive/2010/10/27/ballmer-micr...</a><p>"Interviewer: "HTML or Silverlight, what is Microsoft's lead strategy for developing rich internet applications? Silverlight, HTML5, or acquiring Adobe?"<p>Ballmer: "If you want to do something that is universal, there is no question, the world is going HTML5... The world is just pushing down that HTML5 path, and so are we... What we've really done [with Silverlight] in very good ways is to repurpose it as an important part of the client platform, so yes, you will embrace HTML5, but it's also clear people want client apps... So we're dedicated to Silverlight, but with a little different concept, and we're embracing HTML5."
