David Ogilvy said 'You have to attack people through the eyes and the ears' or something along those lines when referring to text on flip overs and what you say. As in, the spoken and written text needs to be exactly the same in order to land the message. If you speak different words than are written, he says, you are doing it wrong. I don't know if I agree with text vs no-text, but I do feel what Ogilvy says about this subject: it is so distracting when a speaker uses different words than his slides, even if ever so slightly. I also love the sticky image of 'attacking through the eyes and ears'. Again, not 100% sure these are his exact words.
