If you were to upgrade/replace your M1 today, which model would you go with? My fav laptop of all time was the early generation macbook air laptops. They just really nailed the form-factor, weight, screen size, combo on those early models. 

 Framework 13 

 wow... looks like a very nice option for amd64 + linux 🤔

 I’ve also got an M3 pro and its an absolute monster of a machine. I love it but it mostly stays on my desk plugged into my monitor. So its more like a desktop machine that I opportunistically use as a laptop.
