I think we must separate here. We have two “users”:
-Those who upgrade yearly
-Those who don’t.
I think that yearly upgraders can do whatever they want and it doesn’t matter - after all, they can accept anything and everything and they will have a new iPhone the following year.
I belong to the second category: I keep iPhones forever and never update iOS. I upgrade when the original iOS version is too incompatible, or when I feel like it.
I’ve used the 5s, 6s, 7+, Xʀ, and after a long upgrade break, my current 16 Plus.
For long-term users, I struggle to see the point of the Air. Sure, yearly upgraders can take as many feature hits as they like because it doesn’t matter.
Long-term users:
-Only one camera, which a flagship-level iPhone (or one at this price point) hasn’t had since the iPhone 7 or the 6s, depending on how you consider the Plus
-No Macro
-No stereo speakers
-No Ultra Wide
-No Cinematic Mode
-Battery life TBD, video-decoding efficiency notwithstanding.
-No mmWave
All for the amazing discount of… $200 more expensive than the base iPhone, which has all of this.
So, I’m not upgrading, but if I were (say, if I had the iPhone 11, or 12), why in the world would I choose the Air? It costs more and I get less. If battery life were significantly worse for general usage I’d even lose battery life, depending on the iPhone I’d be upgrading and its battery performance on its original iOS version. I’d need to see real-world battery tests though, and I might be wrong about this.
But with all of this missing, why would I buy this to use for 4+ years? It makes no sense at all unless I REALLY wanted the thin design and unless I were okay with the constraints (which I am not, I’m not going back to a single-camera iPhone).
