I think Apple's era of unreliable laptops were the ones with Butterfly keyboards. So many issues back then, but they did a complete 180 once they reintroduced the magic keyboard and then Apple Silicon.
Apple Intel laptop + a butterfly keyboard was the absolute gutter tier experience. Not only it was slow and ran hot, but after a few months a random key would get stuck and stop working.
I was gifted a Touch Bar and bought an M1 air when they came out. It was a night a day difference. Fan speed and throttling killed the experience and Touch Bar was not good.
