Currently most conferences either happen in person, on a speaker phone or on some sort of voip system.  Skype, gotomeeting and line2 are just some of the more popular options.  However, if microsoft is right on what they expect, those applications could change a lot:

You have to have Microsoft’s bulky augmented reality device strapped to your face to see the holograms.
And you’ll also need to be surrounded by cameras to send an image of yourself, so it’s not exactly as simple as using a phone or webcam.
But Microsoft wants it to be “as natural as face-to-face communication.” So maybe one day a bunch of holograms will be sitting with you during business meetings in the conference room.

And here is a reported update on how big this could actually be:

There is a growing sense of anxiety among tech giants of the Samsung and Apple variety that we may have reached “peak smartphone,” a point at which demand levels off and sales plummet. You could argue when adding beveled corners to a device becomes a major selling point, a la the Samsung Galaxy S6 Edge, it signals meaningful improvements have essentially stagnated.

What do you think will companies deploy this?  And if so will it add to the productivity of a meeting?
