Yes, perhaps it will be like the MacBook Air and it will eventually gain those features, but today I don’t really see the point.
Maybe it will become the default, but right now it’s a compromised iPhone 17 that’s more expensive, and whose only two advantages are thinness and weight, on the one hand and grouping them as a category (which I don’t care about), and if you like, screen size, but it’s barely larger than the 17 and a little smaller than the 16 Plus. Apart from that, it’s all drawbacks.
I think you have to be really bothered by the weight of the regular iPhones to get it for long-term use.
I think it’s a good upgrade from the Mini if you can lose the Ultra Wide. Obviously, especially if you like the Mini because of weight. Better battery life (a key issue of the Mini), in a thin package. Ergonomics will be tougher as it isn’t small, but the Mini’s days are counted anyway. If battery life was poor on iOS 14 and 15, it won’t be good at all on iOS 26.
Otherwise… I’m just not seeing it right now.
I’m not upgrading from my 16 Plus on iOS 1&, but if I were, I pretty much immediately rejected the Air as a possibility.
The only interesting aspect of its drawbacks is… that for the first time ever, Apple included full portrait mode on a single camera lens.
As a user of my beloved iPhone Xʀ running iOS 12 for 5.5 years, it was the only thing I missed from the Xs. It wasn’t a technical limitation after all. I wish I had it on my Xʀ.
