My old SE died just before christmas (the battery would often drain to 1% straight away after unplugging from the charger, so it made it rather unreliable).
When I went into the second-hand phone shop, they looked at it like it was some sort of artefact, and when I asked for the smallest iPhone they had, I got looked at like an artefact!
Phones nowadays have become ridiculously big. If you don't live your whole life on it / run your influencing business from it, there's really no need for them to be so big - they don't fit as easily into a pocket, etc.
I ended up with a second-hand 13 Mini, which is only a bit bigger, but feels a lot larger in the hand. There's much more screen space than the old SE, though, which is nice!
Remember the days when they were just getting smaller and smaller? Zoolander was pointing the way!
