Overall, pretty good considering it’s low price. It is a bit quirky, kind of like running Linux on a laptop 15+ years ago. Hardware support is somewhat lacking because it’s all pretty new. That said, the default Manjaro that ships with it works pretty well out of the box. It struggles a bit with video conferencing, in my case, roll20. It can play Minetest and Supertuxkart on minimum settings.
Yes. Microsoft is the king of “good enough” software. DOS was good enough (and had a free C compiler!). Windows gets the job done 95% of the time when it’s not freezing up or needing rebooting. Office is okay - and nothing else is 100% compatible so you get a bonus of vendor lock-in. New features are few and far between, as are bug fixes for non-critical issues.
