That was my very first thought as well. I'm wanting to build a display that can show the status of various things - garage door, temperature, air quality, etc. Ideally it could run on battery too so I could mount it anywhere. Just need to find the time and motivation to do it, among all the other priorities & interests.
Maybe if they supported touch.
Not really, not everyone likes or wants touch, and the fingerprints on screens.
Switches, buttons, sliders and knobs are excellent physical input devices when used properly.
