I agree that the newest model isn't always strictly better than the old model. I still have a 2013 Macbook Air that loyally travels with me everywhere; I bought it new. In that respect, for something that I use (almost) every day I think buying new has worked out well for me, and whenever this thing gives up I'll certainly buy my next laptop new as well (Mac or otherwise).
