Similar experience. In active use in my house:

    2012 MacBook Pro
    2015 MacBook Pro
    2019 MacBook Air
    2020 M1 MacBook Pro

My first gen 5k iMac (2014) is our kitchen machine these days. Still a joy to use. The final gen (2020) model is still my main machine.

I almost wish one of them would konk out so I can get an M series, but then I wouldn’t be on a 5k iMac anymore, which would suck. Love these machines.
