My previous one, a 2015 mba, runs like garbage now. It's the slowest thing you can imagine.
My equally old linux laptop runs just fine though. Not 100% as fast as before, but there's so much less cruft that it's still good to use.
The mac I returned had 8gb of ram and was meant to be an internet box, but the m-series aggressively uses swap memory to burn out the SSDs and force you to replace the entire machine within a few years. It's nuts. I had 1TB of SSD writes in a single day when I downloaded and installed nothing due to all the swap being used--7GB. That was just web browsing. The same workload on my old 2015 mba uses like 6-7GB of ram and no swap.
At 1TB per day of writes to swap, the lifespan of the machine was going to be extremely short
It's so gross.
I don't know what I'm going to do for my next laptop. I wish more companies could make good keyboards
