Seth Godin posted today about powerpoint and how it is so often misapplied. If you've sat through any powerpoint presentation, it's probably been bad. People love to have bullets and list out exactly what they are saying. The problem with that is that I can hear. I understand what the speaker is saying so I don't need to read the exact same content. Seth offers some great advice on how to use powerpoint to deepen your presentation.
On a related note, this powerpoint presentation cracks me up because it's so bad, but that's kind of the point. JM
