You missed the point that the iPhone 7 and 7 Plus were also for sale during this period and quite well still.
HO HO HO!
Doesn't say much for Face ID's popularity. Apparently way more than 55% of people still wanted the Home button after all. All in all, I'd say the huge winner was Touch ID.
Pretty much what I predicted and was laughed at for saying. The Home Button and Touch ID are sound solid tech.
All these new gestures and mistaken touches to me lead to a "bag o' hurt." Too many things to remember. Apple is about simplifying things. Taking the home button away unnecessarily complicates a lot of things in my opinion.
But what do I know? The buyers have spoken.
Tim Cook, the bean counter, should have noticed this. What will happen when there is no Home Button iPhone left in the mix? Hmm.
THey have to start somewhere. Face ID will be better in the long term and the same for the guestures.
Also I think the more important fact was the X sold more than the 8.
With the release of the X+, almost certainly the X & X+ will be the go too.
