YMMV I guess. My Mac longevity has been less impressive, MacBook Pro I got for college lasted 4 years and then went totally unbootable, and the Air replacing had its audio inputs/outputs die around 3 years. I dragged that one out for a while longer with bluetooth headphones and replaced it when the 2016 MBPs launched, which as you mentioned have keyboard problems. Otherwise still solid, so maybe this will be my first 8-year Mac. My iPhone SE 2016 is >4 years though, so I'm doing above average on that one at least.
