In which case, the whole FaceId thing feels a bit of downer. The explanation - "you see how the notification is closed when the screen is off and opens up when you look at it", is at best a nifty trick for people who are more technically oriented. Others might not be able to tell the difference at all.
And on the point of:
" The most attractive customers to Google’s advertisers are on the iPhone — just look at how much Google is willing to pay to acquire them — and while Google could in theory convince them to switch by keeping its superior services exclusive, in reality such an approach is untenable."
Isn't this more to do with demographics of an average iPhone user rather than iPhone as a platform? One might argue that both are related but using this as a reason seems kind of superfluous.
