I used to use a feature phone and I genuinely didn't miss any of the same things.
my commute is a really long ride and I just don't like using my phone in it.
My dumb phone had music system and sd card (I finally managed to have that sd card fixed after an year of using that dumbphone without even an sd card for music)
I just used to stare into nothingness / surrounding and think. (Yes I have edited it because I didn't used to think, I used to overthink just as I am doing right now lol)
Not that productive, but my current phone is so slow that I can't even tell you guys or start telling you. It takes me 1/2 a minute just to unlock it and the only thing its truly good at is having a music player run and some occasional hackernews or pokemon showdown or youtube scrolling.
But tbh, I don't have any banking apps etc. so to me there isn't thaaat much of a difference. I feel like a macbook is genuinely nice as it has that less friction and a pc is great too as compared to a phone for the most part when I am at home.
My screentime is usually just some shorts that I occassionaly watch on phone when I am extremelyyy bored.
I am sad that my dumb phone was in my bag one day and then it just stopped (working??) , I swear I kinda regret having my dad's old phone. I am not sure how he was even using it.
There's a much bigger likelihood of me going back to a feature-phone, compared to me starting to use my phone for anything but the absolute basics.
