This was even true 15 years ago, when I was CTO for a startup that put displays on restaurant tabletops. Even back then (before the iPhone was even released), we saw that most users tried to touch the screen to control it! People reasonably expect all screens (especially any screen displaying information) to be touchscreens they can interact with. We need the hardware to catch up. Fortunately, newer technology now makes it possible to build large (up to 100 inches or more) touchscreens with no compromise.
