It looks cool, but that round switch isn't as useful as it seems. It would've been better if they simply put three buttons up there - switching between devices

It looks cool, but that round switch isn't as useful as it seems. It would've been better if they simply put three buttons up there - switching between devices would be easier (push of a button instead having to move your hand to the far left and turn a knob) and faster (switching from device 3 to device 1).
