I use the M1 Mac Air for office work. It replaced my 2017 MBP, and the difference is very noticeable -- with some 3 dozen tabs open on my browser (not the best of browsing habit) the M1 can take it without breaking a sweat. Yet for entertainment and hobby programming I revert back to my (really) old 2011 iMac that runs High Sierra -- I have invested much time fine-tuning that machine. I tried to migrate the setup to the M1, but a bunch of dependencies were broken. I'd stay with the iMac for as long as the hardware can hold out.
