GWT-Gears: The Browser is the Platform

This is a great hour-long presentation that I saw on InfoQ a while back: http://www.infoq.com/presentations/gwt-gears-browser-platform

Summary:
This presentation explains how and why to use GWT and Gears to create rich internet applications that can also be run off-line. GWT basics like java/javascript integration, Widgets, RPC support, unit testing, CSS, and the debugger are covered before introducing Gears as the means for off-line delivery. Together, GWT and Gears "makes your browser the platform."
