i personally wouldn't go that far. the SE1, as of today, is still a good device. i can use the apps i need, watch video's, take pics/videos, send email, text, play music, make calls, etc. i have decent size hands, and i rest it on my lower finger and use my thumb to reach all 4 corners, and i like the home button. it's a nice device.
i've had an SE1 since 2017. the size is great, battery ok, fits in any pocket fully. my first was a space gray 128 gb. it suffered a bad screen situation (though still partially functions). i purchased a friends 64 gb version in that emergency ( they had bought a 13 mini). now the 64 somehow suffered a right side vertical screen issue, so i have activated a 32 gb SE1 i had recently inherited. 32 gb is way too small, and the battery is headed to 90%.
so, choices were a new SE1 128 for $150, a refurb 13 mini 128 gb for $400, or a new 16e for $600. so far, decided and ordered the SE1. it will have good storage, a factory battery (sealed box), and all the built-ins i use. maybe it will buy me another 12-24 full use months. by then, i may grab a refurb mini.
for this year, i will use the 128 gb as my primary number and protect it, and the 32 gb as my work phone.
