I plan to use it, until I need to charge the battery every 15 minutes.
The larger phones barely fit in pockets, fit poorly in running packs/biking gear and are just generally inconvienient for being active with them.
I also write software for these beasties, and it may well be that I won't be able to justify avoiding getting one that has Apple Intelligence.
I'm still hanging on to my perfectly working iPhone 7, while app developers tell me to fuck off left and right. It does everything I want a phone to do, but developers consider "old phones" to be icky and stop supporting them.
