Actually it works quite nicely on a M1 14''. Even battery life is quite good. Compared to my Dell XPS 15 7590 it has twice the battery life, easily if not even more.
One thing which bothers me a lot as it makes the laptop hardly useable for me at night: display brightness cannot be adjusted, it is either off or 100%. Some user claim this can be accomplished by installing the asahi-edge kernel, which does not even boot for me.
And this also bothers me lot: why are things checked in/distributed which do not work at all in Asahi Arch?!?! If you install e.g. a dev kernel which does not boot because the NVME driver is broken and you do not have a fallback kernel you are doomed. You cannot mount the partition in macOS to fix this manually.
