I'm still using my 2015 13" Macbook Pro. I bought it in April 2015, and I think I'll actually get ten years' use out of it. The form factor is still decent, and it generally runs cool and quiet, but the performance is nothing to write home about (shall we say). It's still useable, for now, but it's becoming increasingly obvious that nobody is optimising their software for this tier of system any more.
You do have to be pretty determined to squeeze 10 years out of this sort of laptop. macOS gave up on my laptop a while ago (it runs macOS Monterey), and the app store moans at me occasionally about not being able to upgrade this or that because I don't have a recent enough macOS. It seems Apple gave up on selling replacement batteries for it at some point last year, too.
I replaced my kid's 2017 mac she used through university last year. I expected it to be trashed - and turns out it is in reasonable shape. While it looks like this might be the last OS refresh for it, it felt usable. 16G of RAM probably went a long way. Cleaning it up for a second life.
