This is the most important thing to consider. The way you photograph and look at things will change with a rangefinder. The biggest difference, for me at least, is the ability to see what's outside of the frame and I absolutely love it. That and the fact that everything in the viewfinder is always in focus makes rangefinders a very different shooting experience, you should be able to understand why street shooters will find these two facts beneficial. I started my rangefinder journey with an Olympus 35 SP and fell in love with it. Since then I have gotten several other fixed lens RFs and just this week I received a Canon P which is a camera I've been lusting after for a while after trying out rangefinders. I still shoot with my manual focus Nikon gear, but for most "general purpose" photography (as well as stuff like street) I prefer the rangefinders. They just feel right and are more fun to shoot with.
