Personally I don't use Apple because I have far too many things I can't do on it (mostly due to their restrictions in the app store, like using open PGP keys over NFC). But if I did I'd never consider the SE.
I mean, it makes the phone smaller for the same screen size. That's an improvement for me.
Not enough for me to drop $$$ on an iPhone-mini, but I'd be happy if Apple put future SEs into an "iPhone 13 mini" body (presumably with a single lens camera).
On a tablet you can use them to hold the device but a smartphone is small enough to grip by the edges only.
And OLED really is a total must-have for me these days.
It's definitely a great feature if you wear a mask often. I find I only have trouble with it if my finger is wet.
But what’s the problem with FaceID?
If you combine the SE with the local used market, it can get extremely inexpensive. I'm currently rocking an SEv2 that I got for $150.
I'm not saying that $150 is cheap objectively, but in relation to Android phones - even used ones - it stands up pretty well.
This is especially true since Apple supports phones for so long. If you're cost constrained, you can spread the cost of a phone over more years than a typical Android phone.
