Power Point is Evil?

I can see where Tufte is coming from, there are some negative side effects to power point presentations. For example, no one wants to hear someone read a power point presentation word for word but I think if a power point presentation is done well then it can be very effective. Tufte says that it's become a substitute for a presentation instead of complementing the presentation but that just not true for the majority of power points I've seen. I like power point presentations. I'm a visual learner so if I have something to look at I pay more attention then I would just listening to a lecture. I think the use of the power point gives the audience a more concise interpretation. If you're trying to give a presentation you want the audience to have a similar general understanding of what you're saying. Just by lecturing it's more likely that the audience will drawn different conclusions from your presentation but a power point makes clear points that lead most of the audience to the same conclusion.
