I just thought about it. Imagine an edge to edge ala X display with touchID instead of FaceID? So that means we would’ve not had a top notch. We would have a circular spot in the middle... or possibly a notch at the bottom for touchID. I think it would work.
I don’t mind touchID
TouchID was great. But Apple is all about that IR dot projector now. It’s uses extend far beyond security authentication.
