Today I downloaded and installed Mozilla Lab's Prism. It allows you to run web apps such as Facebook, Gmail, Google Calendar, or even Spiceworks as if it where a local application. It is a slimmed down Mozilla web browser that creates a nifty shortcut for you to use. You can then resize and move the window around as you would any other window.
It best feature is the lack of an address bar. It sounds weird but that can sometime be a big distraction. So now I can have my gmail open and my Calendar open all day long.
