Switched from a 16 Pro Max.
So far, only thing I miss is the dual speakers. The speaker is OK on the Air, and completely fine when using Instagram or Tik Tok, it only matters when you watch something landscape, it really sounds terrible then.
I have since noticed today that charging by USB C cable is slower, which is I'm irked by, but since I charge overnight, not the end of the world (I don't use MagSafe, I don't like how it leaves a circle mark on the back).
No FOMO on screen size, the Air has a pretty big screen.
Proud to be a beta tester for the iPhone Fold next year...wouldn't be surprised if they keep the Air name for the foldable...
