Grunts have to live with stuff because they have no other choice. Pilots are zipper suited gods whose complaints actually matter.

All joking aside, they have human factors experts work on the UI, and it must go through operational testing- passing isn't a requirement though- systems have been fielded with failing UI evaluations because they were super effective. But pilots still hate touchscreens even though a lot of thought was put into making them suck less.
