The security keypads at work use this terrible design: it's just a flat plastic panel with no moving parts. You have to push the numbers to enter your PIN, but with no buttons, and no mechanical feedback, you can't just type the number in: you have to PRESS... EACH... SPOT... AND... HOLD... while the laggy touch system takes its time registering your input. A daily irritation!
My clothes dryrer has buttons like that. And of course it will ignore button presses if it's not in the correct iternal state yet after you start it up or change modes (which at least is done via a real rotary knob). And you can't just tap the buttons (would be unsafe) but have to hold for 1/2 second. The clothes washer is thankfully still and older model with real buttons.
