> Even when reflections show up on glass displays, it's easy to see past them, because they're full optical reflections with correct depth in stereo vision, meaning that you can correctly focus on the screen without focusing on the reflection.
This... just doesn't track my experience, at least with MBPs up through 2015. "easy to see past [reflections]" is a subjective point even if what you're saying about the optics is 100% correct.
Retina displays are great in some ways but for me a typical open office plan lighting will do the job of providing distracting light reflections on any glossy display, and depth of reflection has never made them any less distracting than, say, someone standing behind me -- sure, you can focus on something else but it doesn't mean they're not a distraction. Not a problem with matte screens unless there's sun-bright direct light. And for outdoor use, sure, that can be a problem, but if I'm picking between any retina model and my mid-2012 non-retina antiglare/matte MBP, the latter has won every time. Which is one of the reasons I'm typing this on that same model and dreading the day it outright breaks or falls out of OS update.
Now if you're more worried about any subpixel smudginess, it's never bothered me, but OK, that's a fair personal preference. And as for scatter through matte from light sources degrading images, outside of bright daylight, I've never even noticed on-screen quality being compromised.
But who knows, maybe your perceptual wetware works differently. And if you like glass/glossy displays, congratulations, you have plenty of options, and that's great. None of that is enough reason to assume it's a global experience.
