Linux systems are usually laid bare for people to tinker with, which for me is specially good if I see something I don’t like, be it software, UI or UX.
Plus, most PC’s I’ve seen from at least the past ~20 years can run Linux, so if I get my hands on a working PC, Linux becomes an easy choice.
Plus², Linux can be made very privacy friendly.
Since 10 y.o. is old enough to be a cutoff for me, PS Vita, and because modding community never stopped. You can even play some Android and PC games through wrappers in it. *-*
