The holographic computer display

I cannot imagine what using a computer would have been like prior to having a holographic display. How could you possibly have worked with a single, small display? You need to able to spread open pages out where you can see many at a time. How else could you work? I would find working with a single display crippling. I have heard that more upscale computer users started adding one or two additional displays. They were the more affluent users, as large displays still cost a great deal. The obvious solution was to bust loose from the physical display.
