Not everyone makes the same amount of money. My mom has a 2017 model which I say is still new. MacBooks are very very expensive. One advantage of a new model is not having to memorize password after password for the advantage of touch id and the apple watch connectivity to the macbook. So the question is what year should my mom replace her 2017 model? Perhaps when it breaks? I know for my 2020 MacBook Pro I wont replace till it breaks since I also do not make allot of money and simply cannot afford a newer model.
