The DoD excels at generating 50+ slide briefs with overwhelming architecture diagrams. It's like they are using PPT as a design tool...

I present my fair share of PPT briefs and as others have said

1. Don't read the slide text - talk (in normal human language) to what the slide is presenting
2. Keep fonts large - no more than 3 bullet items per slide
3. Images/Graphics (screen grabs) are powerful as long as they are relevant to material
4. I avoid animation/gimic transitions whenever possible - YMMV
5. Know your audience

Otherwise PPT is a perfectly fine tool for what it is. Most lousy briefs are due to operator error.
