I never ever use my laptop anymore outside of work. I never surf the web, read, order stuff etc from my laptop. It’s basically useless now if I don’t code or use pro apps. So a bigger phone is confortable because some websites suck on smaller screens and using an iPad is too big sometimes
Most people only use computers at work, solely relying on smartphones for communication, media, shopping, etc.
It makes sense to have a big screen at inconvenience of having to carry it around.
What surprises me is how small the demand for small phones is. I have absolutely no need for a big screen - I have a monitor.
