@varjolintu Aside the bluetooth connectivity issues, I’ve been quite happy. Replaced my late-2012 iMac (did not officially support Big Sur anymore) with Mac mini so it was quite big jump in performance. While kicking butts in performance this computer is totally silent. Never heard any fan noise.
Hopefully BT issues are just signs of immature software / drivers and will be ironed out in the coming updates. In that sense it is not bad idea to wait the next gen hardware.
@toni Have you been happy with M1? I'm still waiting for the next releases before making any moves. Old MBP 2012 needs a battery replacement, again.
