This. My spouse is working on an online business and needed a laptop to carry around to do inventory with. I happen to have an old Asus 32-bit Celeron netbook collecting dust, so I gave it a bit of a wipedown, installed the latest version of Debian with XFCE on it, and let them install what they needed from there.
So if you get a 64-bit machine AT ALL, it will absolutely run the latest versions of Linux.
(Why is this a thing?
Lots of computers in industry are very low-spec. They use less power and have fewer requirements. As long as there are people who use that hardware and/or are willing to port fixes and new kernel features to it, it’ll keep getting updates. You only run into the ‘dropped compatibility’ thing when really no one is using it.)
