I'm not sure you fully understand my post. Again, I'm totally willing to go along with Apple's story for a 100% in the way it works. But they're pretty clear in their presentation and marketing that you have to 1) look at your phone and 2) slide to unlock it with your finger.

But this is much slower and are far less flexible than picking your phone out of your pocket, or from anywhere else, with your finger on the sensor. And nobody is mentioning that this is a downgrade.

You see, FaceID is not 100% new. Face unlock existed on the Galaxy Nexus. It also existed in much improved form on the Lumia 950 and Galaxy Note 7. I will 100% grant you that FaceID will be far more accurate still than these implementations. But accuracy is not the issue here: all these methods imply a two step face unlocking ritual, which again is a downgrade over no ritual with a fingerprint scanner.

In the end it seems pretty clear to me that face unlock - in any form - will be far less seamless than finger unlock. It makes your phone slightly less easy to use. Yet Apple seems to be successfully arguing that it's an upgrade or at least an equivalent. But it just can't be, no matter how good their implementation is. That's what I don't get.
