I've been a Pro user for years, mostly because of the better screen and camera flexibility, but increasingly I'm finding myself taking photos that aren't as demanding, and prioritizing weight and size. I went with the Pro last year because the Pro Max in a case with a magnetic wallet attached to it is a 2lb brick that simply destroys my pockets.
It may be a mistake but I am going to try the Air this year. Bigger screen than the Pro I have, but also 2 oz less weight would be welcome. My wife has the better camera now, so the compromises may be ok, assuming battery life is indeed equal to that of the 16 Pro (27h).
