[dba-Tech] PowerPoint and resolution

Now, I've always read that you should reduce graphics to 72 dpi because 
that's the best you're going to see in a presentation -- and accommodate 
individual graphics accordingly if you need better print quality or you're 
outputting to film slides. This guy says that doesn't apply.

Anyone want to shed some light on this for me?
