In replica to a post of one of my friens that you can read here I have som questions:
Better do the talking while "walking" (along the room or together with the audience)! as the ancient Greeks were doing. so U will not need Internet access. :) and another point: why is it that TV or viral advertising is so nice to all of us while "advertising presentations of the sponsors of a conference" are most of the time boring? What do we want in fact?
