It's the Apple modus-operandi of late, take an existing technology and improve it to the point where the friction is non existent.

Sure, many devices had fingerprint scanners before Touch ID, but the Apple implementation was pretty damn impressive compared to what came before.

Still, I can't help but feel that Face ID is a fudge they resorted to because they couldn't get Touch ID working through the screen reliably.
