When I was working at Amazon a few years ago, PowerPoint was banned for most employees (at least for engineers and their immediate management). It was refreshing to see that the presenters had to be prepared to communicate a well thought-out topic, instead of relying on the slides (or worse, reading out the slides verbatim). Any dense form of communication had to be done in writing beforehand.

In my opinion, slides should only be used to visualize information; charts, digrams, illustrations, etc. They should also, sparingly, demonstrate the structure of the presentation; think of it as a serialized version of your mind map. Any more information should come from the presenter otherwise.
