> Like how do you do your homework WHILE playing Minecraft and watching a movie if you have a display over your eyes vs a monitor or two?

Pretty simple really: You simulate as many virtual displays as you want in any position/configuration you want. Thus making VR actually superior than even the best PC setup for multi-tasking.

That's not really viable today though. Comfort, resolution, tracking, input - these all need large improvements first, but eventually it will out-PC a PC.
