I personally would love to see a proper graphics application. I would use linux as my main PC in a heartbeat if a Sketch equivalent was available. I expect a lot of people have similar feelings or have one thing keeping them from completely making the jump.
I recently got a MBP and the fonts are great. In 2016, Linux needs this fixed.
That's like saying some art dealers don't care what paintings look like. They just sell the stuff.
I know three types that I use: serif, sans-serif and monospaced programming fonts.
I do however care a lot about keyboard layouts, keyboard shortcuts and general snappiness of the OS so I am definitely a programmer ;-)
Edit: and I'm not a graphics programmer so I'm not an "art dealer" anyway, more like someone in logistics. :-)
Long version: It seems there are two kinds of people here:
Some like me never think about any font that finds its way into any mainstream distro.
Others seems to care deeply about them.
I find it useful to keep this in mind as I honestly find one of the highly praised Mac a usability disaster (tried honestly to work with it or around it for almost three years).
