I'm on an M1 MacBook Pro, and had to check settings to remember it's almost three years old. Zero issues, performs wonderfully, probably going to keep for at least another two.
Same, bought an M1 16" MBP w/the Max chip, basically all the best specs. Unless there's a titanic shift in performance I probably won't be buying any new laptops for a while.
I'm on an Acer 16GB/1TB laptop from 2015 that runs as smooth as day one (Ubuntu). I think the workload just hasn't increased much except for gaming and some niches like GPU workloads.
Also using the 2020 M1 as a work laptop. If you stuck the internals in to the new case and told me its the 2023 model, I wouldn't notice it wasn't brand new.
Dock it to two - the M1 can only handle one external display; the previous Intel MacBook Pros could do four; and the M1 Max brings this back. I have four external monitors + the internal and the M1 couldn't do it; the M1 Max can so I held out.
