I need the M2 for business communications and software, e.g. my accounting system. I also want to stay compatible with the other family iOS systems. I might dual boot Asahi at some point.
What I’m most interested in is converting my 2012 Air to Linux for development purposes. The hardware is good! With 4GB, it’s really too small to run recent MacOS, and it will be unsupported soon, but it should be fine for i3/Linux.
If you need to install Asahi, you should install it as per the instructions in a dual-boot setup, then delete the macOS partition and resize afterwards.
