Sure, but it’s still not straightforward - e.g. 2012 saw a switch to Retina display and SSD storage as standard, so it’s not really comparable with the “classic” low def, spinning rust model that came before. The 2019 model went to 16” with no price increase and, as I recall, offered somewhat better bangs-per-buck.To be fair, some of those had previously seen price increases.
Looking further back, I paid the equivalent of $2500 for my 17” MBP in 2011. The 2021 16” blows it out of the water for the same price... so how far back does it make sense to go? Looking at a PowerBook G4 or something would be absurd, but (if the GPU hadn’t blown) the 2011 17” would still feel much like a modern Mac 10 years later. (C.f the evolution from Apple 2 to the original Mac over less than 10 years).
Thing is, we’ve had 40 years of hyper-deflation of computers (if you take the growth of specs into account) - huge price drops in the first 10 years, stable “numerical” prices - with mushrooming specs and no regard of general inflation. I think the “chip crisis” and slowing down of development (harder to get people to upgrade) may be the end of that.
