The keyboard offers three buttons to switch between different computers, GREAT, but the mouse doesn't follow along for the ride... There is a similar button on that mouse, that's small and on the underside, but then the mouse gets out of sync with the keyboard so you'll type on one machine and move the mouse on the other. Seems like such an obvious feature, but if you were hoping this combo would allow you to only need one keyboard and mouse on your desk for both your work laptop and your personal computer, well it just doesn't work that way. Very disappointed.
