But you forget one thing...
software weighs nothing, and takes no sensor input.
BUT the extra switch weighs something..(not a lot i know.. but it can make a difference) and takes an extra sensor input that if you have a very complicated robot with lots of sensor inputs and such, you may not have the extra sensor input to spare.
just a thought
