Indeed, a well "curated" PC built specifically to run Linux is a beautiful thing. Now that I know how to do it, I don't see myself going back to Apple for anything other than my phone any time soon.
I see people having a really hard time trying to do basic things like run their displays at a reasonable resolution on Linux, even on premium hardware - some apps seem to scale badly for some reason? Most non-Apple laptops seem to only be available up to HD resolution as well, which seems absolutely crazy to me.
Actually, I see a lot of non-Apple laptops offer HD (1080p) displays, with the only upgrade option being 4K, usually at a price premium of $300-$500. That's even more annoying to me. Lenovo is one of the few manufacturers I see that allows you to step up to a 1440p display for a moderate cost.
