I love the fact that System76 is an American company pushing Linux forward (well to certain degrees, anyway). I know they use hardware produced in other countries (for chassis at minimum, not sure about the rest of the components), but it’s still nice to see.
Next time I’m in the market for a laptop, I’ll certainly give them a solid look (hopefully the form factors of the more powerful systems will be less…girthy…by then).
Pop!_OS is quite solid. I’ve used it from time to time. However, I’m partial to Arch because I like to be closer to the bleeding edge (currently using Garuda for my gaming rig).
