I get the "just works" with decent privacy aspect of the smaller iPhone, health benefits from Apple Watch and for anything requiring longer screen time, termux, shelter cloned apps etc. I use the bigger android (Infact I'm typing this on the excellent HN client Hacki from android).
Earlier I used to use Apple Watch with android using a tool I built[1] which now serves notifications from android to my iPhone.
I'm glad Eric is going ahead with the small phone.
