Well so far, the very first demo of FACE ID was a complete and utter failure. So we'll see how that embarrassment shakes out in the media.
As for Apple being leading edge, sometimes they pick a tech to kill that actually hurts their market share.
I watch eBay sales, iPhone 6s prices went up when they dropped the headphone jack and I see iPhone 7 sales going up with this current launch. I just think there's going to be a lot more skepticism of Face ID after the failed launch. Tim Cook's a bean counter, hardly a visionary. Steve Jobs is dead. He didn't give Timmy the Reality Distortion Field. Steve Jobs could have sold Edsels in droves for Ford. I"m anxious to see how Timmy gets through this. Unlike Jobs, he's not a media darling. His charisma could fit in a thimble.
The glaring thing about Touch ID is that Tim Cook was seen unclothed. Steve Jobs would have never let anyone know that Apple failed at getting Touch ID under the screen. You wouldn't even know about it.
You'd only know there's this AMAZING ONE MORE THING called FACE ID!
