The button that replaced all buttons, then became one giant button.

means A display that senses the touch of a finger (or stylus) and responds, letting the screen itself act as the input device.

from A straightforward compound of 'touch' and 'screen' — the technology dates back to early capacitive and resistive sensing experiments in the mid-20th century, with usable touchscreens emerging in research labs around the 1960s-70s. The name just describes exactly what it does: you touch the screen instead of a separate control. No hidden story here — the honesty of the phrase is the whole point, right up until it swallowed every other interface.
