> my 2013 MB Intel still looks and runs great

I switched to MacBook in 2017. My first MB was a pleasure to use, solidly built and the keyboard a delight for a touch-typist.

But then Apple got crazily fixated on making them thin. By God they are some of the worst physical devices I've ever owned. That butterfly keyboard is so bad to the point of being non functional.

Fortunately they course corrected with M1 onwards. I still have their immediate predecessors of M1 as a secondary/backup device. While the spec is maxed out the physical device is just bad.
