Pixel density is a huge issue. With current Oculus and Vice displays, you can not only distinguish individual pixels but also see the red, green, blue subpixels. I can't imagine doing work with that. Only some specialized tasks could work, I can see how Tilt Brush could work in CAD work. But projecting your usual 2d app windows to VR sounds awful with the current consumer products in mind.
