NetJaxer is an interesting app that lets you treat your web apps—Gmail, Ta-da List, Writely, etc.—like normal Windows apps. With NetJaxer you can create desktop and quicklaunch icons for them, make them run when Windows starts, and minimize to the system tray. When you run a web app with NetJaxer it's loaded in a NetJaxer window, which is basically a dumbed-down web browser. It sounds handy for people who always have a certain set of web apps running in the background and want an easy way to make them pop up at boot and get out of the way when not in use.
