Your take on a Microsoft/Sony VR headset.

Ever since the Xbox 720 roadmap leak, rumours about Project Fortaleza and Sony's own VR headset have been wandering around the internet.

What do you guys think about VR? Is it the future or is it a glorified tech demo? Would you use it and so, in which scenarios?

Asking this because I am not sure if I have to be excited about this tech, as it's still a completely unproven technology (unproven in a way that we have no clue it will be succesful/if it will catch on)
