I read about it on penny-arcade (towards the bottom) and thought I'd give it a try.
Its kind of a plug-in/shell for IE. It allows for multi window browsing, has a built in pop-up blocker, and a bunch of other stuff.
It works pretty well. The interface is a little cluttered, but the functionality is good.
Just thought I'd throw that out there.
