Interesting article about the spreading nuisance to generate Powerpoint Presentations consisting out of several slides for topics easily summarizeable in a few sentences: Toyota chief: refrain from using PowerPoint. The Toyota Motor Corporation CEO Katsuaki Watanabe got to this topic while talking about cost reductions:

Watanabe said that (in the good old days?) they used to use one piece of paper to make a clear point or proposal, or to summarize an issue, but now everything is in PowerPoint, he says, which uses many sheets of paper and expensive colors...but it's a waste.

In my personal opinion this slideuments waste something more precious than paper or printer colours. They are wasting time!
