sorry MacBook Pro.

I bought an M1 MacBook Air when they announced the Studio when I was thinking the M2 Airs were coming. I have no regrets other than that maybe I would like the form factor of the M2 better? M1 is a crazy nice machine and for how I work, I’m not sure I would even notice a difference with anything more performant. I’ve had zero issues with lag and I’ve only seen the Spinning Wheel of Death twice since I got it a little over a year ago (and I spend a gross amount of time on this thing).
One sort of funny “con” I ran into to illustrate this: I never bothered installing any kind of visual CPU monitoring in my taskbar on this thing and recently I noticed my battery was draining reallllly quickly. It would last less than an hour! I didn’t think about it too much at first since I’m mostly always on power and there were no indications anything was struggling (even when not connected to power). I finally realized that I had recently started up an old Rails app that my current work uses and I’d never shut it down. There were 3 Ruby processes running at >100% each with no audible indication and no hints at all that anything else might be starved for resources—like, not even a little! I’ve never had that experience before, even on other multicore machines.
Er, sorry that wasn’t very Elixir specific. Other than having to set a flag or two, I’ve had zero issues.

- you cannot run linux in M1 macs yet (but Mac OS isn’t too bad)
Asahi Linux is coming along. https://asahilinux.org/

You already have one. Go into /Applications/Utilities/. The Activity Monitor application. You can put it in the dock, right click on it and by default show whatever activity or activity-history you like. The app’s window shows all the detail, too. I keep it in the dock because it’s a nod to old x-windows stuff.

Oh that’s cool, I never saw those options! Unfortunately, this won’t work for me as I effectively don’t have a dock as it’s always hidden with a long delay for it to show.

Apart from very long battery life - at least half a day of solid work, not just browser or email - and being lightning fast?

Using erlang OTP 25 and elixir 1.14 without any problems. Tests run like 6x faster than older Intel MBP. On the downside… the particular M1 MBP I got has a tendency to iBoot panic. I run docker all the time so I don’t feel any battery improvements.

I had a few aging computers when the M1s came out. I sold off an intel iMac and a MacBook Pro and had the pocket money for two M1 minis and an M1 MacBook Air with some cash left over.
The Air is fantastic, even this far in. The only battery issues I had were when I had this deal with VSCode trying to reindex a codebase and running a little out of control, but that was within the first few months of the M1 release, and MS have long since created a native version of VSCode.
I have no complaints with the mini. It handles 2 28" monitors running at 3840 × 2160 with aplomb. The only pitfall I experienced was having to buy new HDMI cables that could handle the 60Hz refresh rate that the “retina” pixel density requires.
Any compatibility issues I had with needing to get into the plumbing of building libs from source have long been resolved for me through Homebrew, though your milage may vary.
No regrets. Absolutely capable machines.
