I don’t know, you tell me! I’m currently using only a terminal for VERY simple command line entering (and it is only test device and firmware). It accepts only two commands:
fade is the common for both. If It would stay on display, I would be able to correct only last chars
out to “create” a command Let it be ‘use case 1’
OK, another one: A message board (a pager?). I could place a large LED display hanging over in my house, and send from remote location to my wife:“I’ll be back at 4PM, be ready…”. But then a heavy traffic occurred… So instead typing all over again, jus correct "I’ll be back at 6.30PM, be ready…"
I know… the phone is better… but it IS A USAGE SCENARIO
