I like small phones and still use a late 1st gen SE. When the battery died and the screen broke a little over a year ago, I spent $220 at the Apple store getting both replaced rather than upgrade - even ignoring the price of new phones, I didn't like
any of the new phones (even the mini) as much as the old SE. (My wife has the 2nd Gen SE, which is the same size as the base 6-8.)
I'm coming to hate Apple more and more with each passing year. For one thing, I refuse to give iCloud my data, and iTunes, already one of the worst pieces of software in history, has declined into an unusable mass of fail. I would like to be able to play my own music on my next phone, something I've never been able to do with an iPhone, since iTunes insists on transcoding my entire music library and scrogging all my album covers if I let it touch my music. I will not live long enough to undo all the damage it did.
Also, I want an actual headphone jack, rather than having to spend another few hundred dollars on Bluetooth radios I'd rather not have in my ears.
If I have to live with a bigger phone, then I'm going to get something in return - I'm seriously thinking that I might be able to live with a Surface Duo - it is larger, but thin, powerful, and even has bezels(!) so touchscreen scrolling works properly. (The Samsung Z-fold is probably still too large and chunky, but interesting, if still lacking in the bezel department.)
Anyway, it appears that Apple no longer cares about those of us who only want phones that actually fit in a pocket, so I'm done with the bastards. Good riddance, but there are no good small phone options anymore, now that the manufacturers have decided to sell only phablets at $1000+ price points.
Maybe Purism or Pine will eventually not suck. Not holding my breath, though...
