I so enjoy reading articles where people don't really understand what they are writing about. I have participated in telepresence, MS roundtable and traditional video conferences numerous times. There is no comparison. I fully admit that TP is not for the cheap and if cost is the factor, than round table or other solutions are fine. If you are a multi-national company that spend millions on travel and expense between countries and wants to do telepresence where you can see the other person as if they are physically in front of you than the cost is not substantial. But, don't try to claim that 2K worth of audio products will make them the same, that is not even close.
