If you ever have to give a presentation using PowerPoint, read on. 
Seth Grodin has some excellent points on PowerPoint presentations in his blog post: Really Bad Powerpoint
Some of the highlights of this article include:
 
 
Components To A Great Presentation
- First, make yourself      cue cards. Don’t put them on the screen. 
- Second, make slides      that reinforce your words, not repeat them. Create slides that      demonstrate, with emotional proof, that what you’re saying is true not      just accurate.
- Third, create a      written document to leave-behind, and hand it out when you are DONE.
