I think banning powerpoints is going a bit too far. Not everyone is natural born presenter and many can be struggling. Presenting without slides is going to be a major hurdle for these people. What I would propose is that people are not allowed to have any text (besides the title and presenter) on the slides at all. Or maybe a dozen words throughout the presentation. I think it is incredibly insulting to the audience to make slides and then read them literally to the audience (bonus points for title-casing all your bulletpoints and cramming so much text into a slide that it's barely legible).
