I got an M1 on loan while my Intel Mac was in the shop and I was terribly unimpressed. Only 8 GB of ram was part of the problem, but I just didn't notice any performance improvement between it and my Intel Mac.
In my opinion, the Air is the perfect addition to a heavy Linux/Windows workstation. You get the full spectrum from iOS development to gaming, albeit at the cost of having to babysit two or three operating systems. You can use the Air for meetings or conferences, because everything that's not a game has a macOS version (think Microsoft Teams etc.)
