You could have a hybrid which would have good and bad features of both worlds: if you have physical buttons on the side (or all sides) of a screen, and a "reset" button or "mode" buttons. Then the button sequences after "reset" or "mode set" can still be learned by muscle memory, and you don't have to look at the screen. But the buttons can still have multiple uses and the screen can still give directions, especially in the learning or less often used features. The positive click of a physical button is much less error prone than a touch screen (although touch screens with a vibrate function can be a bit better). These kind of displays are used in aircraft and spacecraft. http://astronautabby.com/files/2013/11/Astronaut-Abby-Lockheed-Martin07.jpg http://astronautabby.com/files/2013/11/Astronaut-Abby-Lockhe...
