I just discovered this amasing little gem through Scott. It's called PureText, and what it does is convert the clipboard's formatted text to unformatted text before pasting it to the current window.

By default, it binds to the Win-V key sequence. For example, you select some text on a web page, then press Win-V in a new email, and it will paste the unformatted text, without the web page's formatting. I already can see great use when pasting code from VS.NET! It will save me extra steps.
