Switched to a thinkpad x1 carbon just over a month ago, coming from years of macbooks. I'm over the moon. The trackpad isn't as good, but all the things I use the trackpad for are easily replaced with keyboard shortcuts.
Battery life was pretty decent after autotuning power settings through powertop, too. Better than I'm getting on my current work-issued MacBook, at least.
Only real annoyance for me was the wifi, which would vanish off the face of the earth after resuming from suspend. But I was able to replace it with a $15 Intel, a tiny screwdriver, and some patience.
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.
Pretty much anything else I ever used was more pleasant than that.
The chasis did have abrasive finish too. I'm quite sensitive to abrasive surfaces, they give me chills.
Anyway, maybe I'm misremembering and it was just the chasis. Nevertheless it was a very unpleasant computer.
