For laptop / other display usage is the one (alleged) use-case I don't get. If it "augments the world around you as you roam it", I can get that. But the screen in front of you that you're staring at for hours? Whatever augmentation would be displayed by glasses could be done by a more-chic-than-we-have-nowadays software on that computer, rendering said "augmentations" right onto the display, no?
