Laptop Trackpad Haptics

The trackpad on my laptop doesn't actually click, it uses haptic feedback to simulate a click through a vibration motor. Knowing this has not diminished the satisfaction of using it. The entire glass surface is rigid, but the haptic response is calibrated precisely enough that my fingers believe a mechanical switch is depressing underneath them. Force sensitivity means you can press lightly for a regular click and harder for a force click, and the distinction between the 2 is clear without any visual indicator. The engineering is impressive but the design choice is what interests me. Apple decided that the illusion of a click was sufficient and the mechanical complexity of a real hinge wasn't worth the trade-off in reliability.
