What is a Rangefinder Camera, and is one right for you?

My first digital camera was a rangefinder but I've never shot with a film rangefinder. From reading this article I have gained a better understanding of the advantages and limitations of rangefinders. I think these types of cameras are most likely something I would not enjoy using. Too many limitations, for example, on framing and lenses. I have no interest in seeing what is about to enter the frame. I just want to capture it when it does.
