I actually like using Darktable. And I like using it on a good screen better. So even though I have a Linux laptop that runs Darktable very nicely (even with just Intel Xe graphics), I actually do a lot of photo editing on my 8 year old imac, which has a 5K screen, fantastic contrast & colors, etc. It shows me stuff my laptop is simply incapable of showing. Darktable runs like a dog on it but at least I can see what I'm doing properly and have enough screen real estate to actually fit the tools in the sidebar on the screen without having to scroll.
I'd love to see Linux laptop that is optimal for graphics, movie editing, etc. Mediocre 1080p screens are simply not good enough anymore. Apple stopped shipping anything non hdpi years ago. Even the cheapest macbook air has a decent screen. Decent contrast, easy to calibrate, beautiful colors and excellent dynamic range. Probably best in class by any objective measure. Why can't Linux users get screens that good? It's not like Apple doesn't buy their parts from the same usual suspects in China and Korea when it comes to screens and other things you need to build a laptop.
