My friend uses an M1 as a power user for about a year. Great battery life, almost never uses the fan, super fast, no battery issues, no Linux support with graphics acceleration yet and he cracked his screen and Apple care fixed it. I don’t think the butterfly keyboard is around anymore.
It’s fabulous but so is my much worst Lenovo x250 with 16GB I got, and a new 1080p screen on recently, still very happy with it.
