Powerpoint is a powerful tool in the right hands, but it will not turn a poor speaker into a genius who captivates his audience. You have to craft a presentation so that it's concise and delivers your message with impact. You have thirty seconds max to make your point with a slide; after that your audience won't be listening to you any longer. What you NEVER do is read what's on the slide or overpower the message with useless animations. The message is the thing, and your delivery and presentation have to work together to best get that message into the minds of your audience.
