"On Thursday, the Mountain View, Calif.-based search company debuted the Google Deskbar. The downloadable software for users of Microsoft's Windows operating system puts a Google search box in the desktop taskbar. Using the free tool, people can search for information on the Web while in a Word document or e-mail application. But instead of launching a browser, the Deskbar will display results in a small window in the lower right of the screen." (CNet)
