Fast. Easy. Able to register from tons of angles. I have my thumb and index finger registered horizontally from the left, from the right, same vertically. I know Face ID is the future for iPads. But Touch ID was the best solution without compromises. Push a button... on. Face ID... pick up your iPad and point it at yourself. And the iPad could keep very small bezels and keep the home button. All screen is a marketing gimmick. People eat it up, but it doesn’t compare to the button. JMO!
