The other interesting part to me is that most iPhone users have gotten used to using faceid. I know not everyone likes using it but it is the standard use for iPhone users. The Duo doesn't have face ID, and switches you back to having to use touch ID on a side button like on an iPad. (I assume because they couldn't figure out a standardized position that would work well when you are rotating/folding/unfolding whatever to that could consistently work well.
