They couldn't get inscreen touch id to work...
Isn't that the real reason they went for face id? I would hate it for several reasons. 1. The cost - blimey a grand on a phone should be illegal. 2. Using it on a desk - I often have my phone sat on my desk next to me and reach with my hand, press the button and use it from there. If I had to pick it up, line it up right with my face and then put it down it's just a pain.
Perhaps I'm getting old but I fail to see what I can do with this phone I can't do with one half the price. I may wait 3 nano-seconds longer for an app to load and have a bezel top and bottom. I simply don't care as long as for the few years I have it I get good updates and security patches. My OP3 seems to be giving me all that being already on android O with Septembers security patches.
