I know, I know. And I understand exactly what you mean. I have spent a fair amount of time talking to the "pokers", explaining that just touching the screen lightly does the trick.
I don`t remember the exact phrasing of course, but passengers were asked in what way the screens were practical or impractical, and at least in the ones I saw, the point didn't come up.
Most felt that the touchscreen was more intuitive. Whatever.
