@paco Yes! Touchscreens are not terrible for phones (assuming they are cheaper and more robust than physical keys). Not great, but a reasonable tradeoff.
However, they are terrible for any application where they steal visual attention from important tasks like avoiding oncoming traffic. That goes double when the control surface is modal: the layout of buttons changes depending on function-of-the-moment.
I blame the control panels in Star Trek: The Next Generation.
