All I really need is calls, sms, a solid browser and some more robost messaging apps like signal and matrix/element - I'm a prime candidate for PostmarketOS if we ever get a stable piece of hardware. I have an old oneplus 6 that I've played with it on, its so close. If a flip phone could master that today, sure
I do use tap to pay, but meh I dont think I would miss it and android auto in my car could easily just be a bluetooth audio connection
