> Physical buttons cleanly resolve all of these major problems That’s not true with all buttons. Those infinitely turning dials have some of the same problems, especially with response latency and the same magnitude of input not always resulting in the same magnitude of change. The presence of the dial is better than the touchscreen, but with those dials you still need to monitor the screen to get feedback on how much change you’re (usually slowly) effecting.
