Solid Mobile Phone: Microsoft Silverlight 3 challenges Adobe AIR

Microsoft Silverlight 3 is catching up to the capabilities of Adobe Flash, Flex, and AIR in all the areas where Silverlight was behind. Silverlight 3 applications can run in or out of the browser, online or offline, with much improved audio, video, and 3-D graphics.

Recently I've been hearing from Adobe on a regular basis about adoptions of the Adobe Flash Platform by large media organizations, such as Clear Channel Radio and MLB.com, for streaming media content to the Web both live and on demand. I've been hearing rather less from Microsoft about Silverlight adoptions.

I think that part of the reason is that Adobe leapfrogged Microsoft last winter in the area of media support, particularly H.264/Advanced Audio Coding (AAC) audio and full HD video playback. These and many other capabilities are included in Silverlight 3, which is currently in a beta that does not include a "go live" license, but will most likely be released in July.

Another area where Flash and Flex were ahead of Silverlight is Windows and Macintosh desktop operation. A number of desktop Flex/AIR applications have become popular, especially Twitter clients; examples include TweetDeck, Twhirl, DestroyTwitter, and Seesmic Desktop.
