This reminds me of when I was back in school and the instructor would have stuff in Powerpoint on the projector screen. It was only interesting when a photograph or image would be displayed (this was an East Asian history class) but the rest of the time was just me listening to him speak about the topic rather than paying attention to the slides at hand.

Why? Because he was pretty much just narrating what he already had on the screen.

I have always found that Powerpoint is useless for displaying anything in a meeting or seminar and yet I still find myself doing that when I myself choose to give a presentation. Additionally, I have yet to see anything that replaces it well enough that also mimics the speed and simplicity of the application, and I also find more value in just listening to the person rather than seeing what is on the screen.
