Wait. You're content with your current mac and Homebrew with M1 support only came out a week or two ago. Give it more time to bake. The first wave of M1 products was literally "replace the mainboard component only and leave everything else unchanged", the second wave will probably include iPhone-quality webcams and fancy audio and stuff.

(If you were interestedly in contributing time and patches to fixing M1 software issues on M1, then you could of course get one for that, but you'll want to keep your existing Mac as your primary work computer.)
