Powerpoint is the devils spawn - avoid if at all possible.
I recall an interview I heard on the radio with a senior army officer talking about his experience in Bosnia. Every morning there would be a briefing of the multinational teams he was part of. PP was universally used. They stopped using it after a while when they realised that everybody was planning ops on the basis of the need to get all the detail onto PP. This meant that everything was on the basis of four to six bullet points per slide. Anything more detailed just wasn't covered and important info wasn't being briefed. Worse, plans were being made to fit the ease of putting them on a PP presentation, not operational reality.
The use of PP willy-nilly can serious warp your mind when planning a presentation. Its a bit like gps really - a great tool if used well, but too easily used to gloss over sloppy thinking and lack of planning.
