I own a switch. I have never played it in mobile configuration in the years I have owned it, neither do any people that I know that have it, neither do my nieces or nephews. I would trade switch mobile capability for 4k in a second.
The reason why the switch is popular is the same reason why a long line of absolutely craptastic Nintendo hardware is popular: exclusive Nintendo software, which this platform will obviously not have.
I agree but mostly I think it’s because most games need a special GUI to use a controller. I would buy it if playing factorio and rim world felt natural and intuitive on a mobile platform but it’s not.
