I have an M3 iMac which is my main device but still have an older M1 Mini and it is still rapid! If I want to stream legally bought content on my main tv then I can just pop it in there or grab a monitor from the attic and set up a second computer for the wife.
My main is an M2 Air, so I’ll use the M1 at work so I can finally give my creaking 2014 mini the retirement it deserves. But not before I’ve given Asahi a proper airing on it to see whether I can daily drive it.
