Elevator Pitch

Yesterday I was in a conversation (it was at a coffee shop, not in an elevator) about PowerPoint. I had just a few seconds to pass on the most important things that I've learned about using PowerPoint to someone. I wanted to share what it takes to make a good presentation and how to avoid a bad presentation. This short summary of an idea is often called an "elevator pitch" since it's the encapsulation of an idea that can be shared while taking a short elevator ride. Usually an elevator pitch is about 30 seconds and no more than one minute.

My elevator pitch for using PowerPoint was this (and largely based on the work of Guy Kawasaki):

Use one slide per point that you have to make. Make your points between 2 and 5 minutes long. Use images that take up the entire slide. Keep the text on your slides short and in a large font. Never, ever read from your slides or use bullet points. 

What would your elevator pitch be for using PowerPoint?
