I'm clinging to my 2015 MBP until it breaks, and it scared me a few times recently. So I bought a backup x230 for ~$100 just in case, and loaded Pop!.
To be honest, I think I like Pop! better than OSX. I hadn't used linux distros before because I'm not trying to spend my time fiddling around with the OS, I want things to just work and get out of my way. Pop! does. It's got that miryokuteki hinshitsu. And the ability to use exactly the same packages as our ubuntu webservers has already helped me debug a buildpack issue.
I'll certainly consider supporting System76 when I'm next looking for a brand-new computer.
