I do honestly miss the level of artistic and aesthetic polish that a multi-billion dollar corporation can afford to field that no Linux distro really can.
Linux as a rule is and always has been generally quite "Guys Live In Apartments Like This". Often utilitarian to a fault. UX design by backend devs, because actual frontend devs cost money. No one wants to pay the "beauty tax" for software. DEs like KDE and Gnome are trying very hard and have made great strides, but it's very slow progress.
And I imagine this comment will be a magnet for power user types who will flock to my post and retort something along the lines of, "All that stuff is bloat/a usability nightmare/clutter/gets in my way/comes at the cost of features", blah, blah, blah, waaahhhh boo hiss... Yes, it's all true, and yes, I understand. But Linux and the free software it surrounds itself with tends to be crusty, clunky, and god-awful ugly, and I'd be lying if I said that didn't frustrate me a bit now and again. Does it bother me to the point that I don't want to use it? Fuck no. Windows isn't worth the bullshit. But they do at least know how to make an OS slick and beautiful, when it works, anyway.
I'm sure people will also cherry pick examples of FOSS software that are quite ergonomic and lovely to feel. Yeah, there are many examples that exist, but they tend to be diamonds in the rough rather than exemplars of the ecosystem. For every one dev in this community who actually has a fucking clue how to make smooth-feeling and aesthetically pleasing software, there's a score of devs who slapdash together their programmer-art-tier UIs and call it a day, and a thousand other dev-brained users who look at it and go, "this is fine". And yeah, it is fine. But sometimes I want more than fine.
