I bought a 16" Pro thinking I would need it and realized I never do anything other than simple photo/video editing, occasional VM usage and browsing the internet. Returned it and used the $1000~ savings to book a vacation to the Caribbean instead.
I had fallen for the future proof fallacy when even than, the savings could have been used to buy another new MacBook Air in 3-4 years which would be newer than whatever 'future proofing' I can do now. I would rather buy a new and updated MacBook Air every 4 years with the savings than budget for a Pro model every 7-9 years.
I noticed no difference between using the Pro and Air at all, at least not worth $1000. This sub convinced me that the Air is what 99% of the population would need and is very powerful as is!
I think about this whenever I'm buying a new piece of tech--whether to spend more to future proof and have it last or to spend less and shorten the life span. I've generally opted for the latter.
Because most people conflate "buying a more powerful computer" with "future proofing", which is wrong.
I future proofed when I built my desktop in 2017. We knew am4 was going to be supported for several more cpu architectural generations, so I knew that I'd have an easy upgrade path ahead of me, for cheap. And I did. I went from a 1600x to a 5700x, and from an rx 480 to an rx 6700xt. I fully intend to get another couple years out of this pc, and it's looking like I'll be able to get possibly a full decade of useful life out of it. That's future proofing, and pretty cost effective.
On the other hand, had I bought the best available at the time, which was Intel 8th Gen coffee lake, it would feel so much more outdated and I'd already be in need of another upgrade.
In any case, I'm not sure there's any such thing as a future proofed MacBook. Aren't they pretty limited in terms of upgrade options?
They last a long time because the build quality has been excellent, historically, and also because 99% of the user base never runs an application heavier than a web browser. But then, my decade old windows laptop is also fine for web browsing.
