Hit: Taptic Engine – 2015

A little-known, but world-beating part of every Apple Watch, iPhone since the 6, and Mac trackpad since the 2015 MacBook, the Taptic Engine is the little vibrating motor that provides haptic feedback when you press things on your devices. It makes solid, unmoving buttons, such as the home button on the iPhone 7 and 8 or the trackpad on a modern Mac, feel like they move and click . It makes all the iPhone’s interactions clear and precise and is leagues ahead of the competition, which is still struggling to catch up four years later.
