The point of the exercise is to keep the touch superior sensitive function of the magic mouse, while getting rid of the battery problem and the blue tooth RF. RF is a big problem for increasing numbers of people. The old mighty mouse, which I have gone back to is better than it was. The were problems with the tiny roller ball quitting which seem to have been resolved, but it is no where near as nice to use as the magic mouse, which I have two of. For me the perfect mouse would be a corded magic mouse, my quest continues.............
