Yeah I mean mine isn’t fast but it’s still usable imo.
The MacBook air 2012 was already particularly bad in its lifetime, I remember doing it support for the company I was working for at the time and the air 2012 were only used for lightweight stuff but already so slow.
It still runs decently, I often forget it's a 10 year old machine. I boot Ubuntu on it for work though, and boot Windows on it for the occasional game. It's a useful machine.
My wife's 2019 16" MPB is running pretty great. Probably got another 5 years of life left in it. She uses it to watch YouTube and play Sims 4.
My 2016 Acer Aspire V3-372T is hanging in there running Debian. 60 FPS YouTube videos are getting to be too much for it anymore. I may have to put the old girl to rest one of these days.
I gave my brother my Sandy Bridge laptop that got me through college. New battery and charger and it's all set. The 1366x768 resolution doesn't render pages very nicely anymore, though.
My 2019 mbp is my work daily driver doing fairly heavy design , video, and blender work no problem. Runs well. Probably gets 6-10 hours a day of use. Video rendering a little slow but not egregiously so. It was upgraded to the max though. Its late 2019 intel. Not sure if its on latest OS but shouldn’t be too far behind.
