HTML5 takes another huge step forward with Chrome Packaged Apps. Packaged Apps open-up the desktop to HTML5 developers. Reusing all of the skills mastered for the web and mobile, Packaged Apps empowers developers to create complete app experiences that can be run anywhere you find Chrome: Windows, Mac, Linux, and, of course, Chrome OS!

Definitely worth a look.
