If thats all you do you might as well just use macos. Something comes up you can just send your parents to the apple store. Probably one of the last places on earth you can get a real life human in a real life building from a real life major company to sit down with you and walk you through your issue. They will do this for free, you only pay for an actual repair job, which you can also of course do there for a relatively fair price all things considered for oem quality work. Not sure where I would take any other laptop for repair. Do people even repair laptops as a business?
