"Windows Vista will eventually sport what has been called a 'sidebar' - a kind of taskbar-like user interface element designed to sit on the right or left side of a display and offer 'heads-up' information on a customizable basis. When we last checked in on the Vista Sidebar at CES, we saw a number of widgets (or gadgets) running on the sidebar, including a small picture frame, an RSS list/interface, weather information, and more. The idea, generally speaking, is to give prominent spacing to tasks and information services that are, in theory, so frequently referenced that it makes sense to prominently display them on your desktop, alongside or on top of your other application windows."
