Same here. Have a Base M1 Air. Will trade that for M7 Base Air maybe if I can drag this one for a while. I can't go back to computers with noisy fans. It seems too last generation since the M1 launched.
Even for pretty intense workloads it rarely struggles or slows down. And even with some pretty intense battery degradation (reasonable, to be expected after five years of heavy use) it still runs for more than long enough for me on a single charge, although I really can't go to a coffee shop without a charger if I'm doing development work. All that, and it's dead quiet? I could never go back to the old ways!
I understand the thinking of "I'd like to do local inference on a laptop", but as long as I have a beefier Mac Mini sitting at home that can do all of that for me remotely, why bother?
I can see myself putting Asahi on this thing and giving it to my yet-unborn kids for them to finally drop it down a staircase someday. I've been rough with it and it hasn't broken yet!
I think the interesting part of that sort of success is that if/when this thing will start to lose a step (local inference would be cool, 16GB of RAM is starting to get a little tight, especially for rust builds and agentic programming), I really have no serious qualms about spending $5000+ on its replacement.
In fairness, my Franework 13 Pro is the same, only it gets less hot than the MacBook.
