> Not responding to the fawning per se, but specifically the "unlocking mechanism that is going to be market-defining": face unlock seems undeniably cooler still, works reasonably well, has been shipping on all Android phones for nearly two years now, yet certainly hasn't "defined" any markets.
See, that's exactly what the OP means. I tried to use face unlock on my Nexus 7 - it's just noot good enough. Too slow, too unreliable, especially in bad light conditions. I obviously haven't had the change to play with the iPhone 5s yet, but I'm quite confident that after getting used to keeping the thumb on the home button after turning it on, you won't event notice the fingerprint scanner.
