Microsoft's Silverlight 3 and Expression 3 were released on July 9th to favorable reviews. The original Silverlight shipped in Fall 2007 as Microsoft's first programmable web browser plug-in. It's a 4MB Flash/Flex competitor that runs on Mac OS, Windows, Linux, and mobile devices. While Flash definitely holds the market share for machine installs, according to Microsoft, "In less than nine months since its release, more than 1 in 3 Internet devices now have Silverlight 2 installed."
