It wasn't intended as a jab at all, but I can see how it came across that way. No offense intended, and I do apologize for that. Still, the end-user desktop UX for MacOS and Windows is a major piece of why people use those over Linux as a desktop computing environment. (Nothing wrong with Linux itself mind you, more the ongoing fragmentation, but that's another topic entirely...)

Another important aspect to look at sometime would by typography. In traditional print medium we always used to hear that serif fonts (the ones with the itty bitty hooks on the ends of letters - e.g. Times New Roman) were useful because it helped the eye move along the line. But on computing devices, used to be that the best practice was sans serif fonts (e.g. Helvetica, Arial) because of something to do with the way the fonts get rendered on a screen. That was long before the availability of 4k monitors though, but supposedly it reduces eyestrain and helps with clarity.

I never looked too much into that, and just went with what all the design specialists out there recommended (again, I'm a crap designer). But from this little example we can see that even the shape of the letters themselves plays a role in communicating a variety of things.

Imagine all caps, serif-font, white background, dark blue lettering:

    =  S  M  I  T  H  =
         FOR OFFICE
Comes across as authoritarian, right?

Now imagine the same in sans-serif, black on white, and maybe "for office" laid out beneath the name on the next line, spaced and sized so that the width of each line is identical:

    =  S  m  i  t  h  =
        For Office
Comes across as more formal and respectful but less fear inducing, doesn't it? (HN doesn't let me design here so you'll have to use your imagination of course! ;-)

Anyway, this is just a simplified example of how typography not only conveys the words themselves, but an emotional sense along with those words. There's subtext within subtext possible here, and this entire field is dedicated to communicating more than data, and doing so at a very high rate of efficiency - including the things that don't get communicated well through words.
