New Google desktop tool offers plenty of convienence

From Googles site:
Google Desktop doesn't just help you search your computer; it also helps you gather new information from the web with Sidebar, a new desktop feature that shows you your new email, weather and stock information, personalized news and RSS/Atom feeds, and more. Sidebar is personalized automatically, without any manual configuration required (though you can certainly make your own customizations if you want to).
