Hmm. We’ll have to see how this fingerprint reading stuff goes. Would be nice as a PIN entry alternative for those who use PINs (I don’t). But I am also hearing that existing fingerprint tech is sketchy for those people who do a lot of manual labor, or have dry / rough skin.
Apple is usually quite careful about getting the implementations just right (or at least way better than most tech companies), but I’d wait for some reviews and testing on that particular bit first.
