Most presentations I see are done badly. So badly in fact that they fail at their primary role: communicating content.
A presentation does not have to be a work of art to do its job; presenter doesn't have to be Steve Jobs. Most often it's as simple as follwing basic "rules" for good presentations...
So, the practical advice you find in this presentation is not going to make you present like Steve Jobs. But it will help you make simple, straightforward, competent presentations that help you get your point across. Every time.
