Can you imagine the eye strain one would get programming on a translucent screen every day? One where your always having to keep your eyes focused on semi transparent text and graphical interfaces in the foreground, and not the distracting and ever changing background, continuously shifting in parallax as you adjust your head and viewing angle. Not having my display buttressed up against a wall, or having to deal with glare and screen reflections, or even low contrast monitors in general are all things I find infuriating already.

But I guess the Sci-Fi future of ergonomics is holograms. *You must have your migraines, and you must enjoy them.
