Well, it depends. Having knobs can make a huge difference because you can
-use them blindly (while your eyes are watching the beam spot)
-use two of them at the same time, one for each hand (using a pointing
device for X/Y is not the same as it can be hard to move the axes
separately)
-you can vary tuning speed and direction in a very intuitive way
From my experience people working at accelerators that are rather easy
to tune do not care about knobs. But for machines that are complex to
tune having knobs might save operators a lot of time.
Cheers,
Martin
P.S.: We had nice knob hardware at the S-DALINAC (4 knobs +
touchscreen). See [1] for pictures. Talk to Thomas for details.
