>> How exactly is putting a little scanner inside a button going to be meaningfully better?

Quoting from the article: "Apple's Touch ID was the biggest surprise for me. I found it very well executed and a nice part of the overall experience. When between the 5s and the 5/5c, I immediately miss Touch ID."

Coming from someone as respectable as Anand, I would call that reasonable grounds to call TouchID "meaningfully better".

Maybe you can point to something similar for face unlock?
