Like all MS concept videos, it's all very pretty but useless except for the most shallow kinds of collaboration - it's not so much promising any specific technology so much as a future in which you don't actually have to do any work. How many people do companies really need whose role in its entirety consists of quickly slapping together pretty-looking "reports" full of 3D graphs?

These superficial concept videos have about as much relevance to the world of actual usable technology as porn has to the complexity and compromises of married life. The encyclopaedia we have today is Wikipedia, not Encarta, and no-one cares that it doesn't have embedded videos of antelopes bounding or the galaxy turning.
