The 16" Macbook pro I bought in 2019 has been a source of constant irritation to me - unexpected fan thrashing, overheating, the usual stuff - and the performance and low cost of the new M1-based MacBooks has done nothing to improve my mood.
I have one with 32GB that was provided by my employer. It is bad. I hate using it. The keyboard on it is bad, the performance is bad, and the glitchiness is deeply frustrating.
I loved my 2015 Macbook Pro 15" that it replaced and wondered why I thought it would be any better.
My M1 Macbook Pro 16 is a joy to me.
Incredibly embarrassing to be in a quiet meeting room and accidentally open a slide deck with a gif for 2 minutes and have the machine ramp up its fans to maximum speed. Why?? Meanwhile on my M1 Air I can have the same content open + some Twitch stream + 3D map view open with no fan, no sound at all, and it runs great.
This. Worst Mac I've ever had to use.
