Also people are glossing over the other take away from this:
People seem to be more interested in buying the more expensive Pro phones. So honestly I wouldn’t doubt if Apple knows the iPhone 14 Plus won’t sell overwhelming either, it’s just another means to push customers in that price range to go all the way to Pro. If not? Well now they’re getting someone to make an $899 purchase vs a $699 one.
When put face to face with 14 Plus/14 Pro Max, what do you think they’ll choose? The one with the old chunky notch, 60hz display and 1 year old chip, or the truly NEW device with the DYNAMIC ISLAND, 120hz display and brand new A16. Also if you’re someone that already owns an iPhone 12/13 Pro, it’s probably a given that you’ll go for a 14 Pro as well. I doubt you’ll downgrade to a 14 Plus.
As stupid as it sounds, I think the Dynamic Island alone will be enough to push people since it’ll be the new noticeable thing that lets you stand out from other iPhone owners.
