I don't agree it'll be less useful. Actual telepresence has a lot more possibilities than just a video stream. You could interact with people in the virtual environment, build or design something together, brainstorm in new ways (For example, imagine architects designing a building while walking in it in realtime), and take notes digitally. Once you can do everything in the virtual "world", you don't need your hands/eyes free for other things. (and I'm sure there will be a pop-up HUD interface in which you can do other things if you really want to be distracted like browsing HN during a meeting :).
