I love speaking and especially love speaking from minimalist slides. I'll have whole chunks of the presentation where the slide is just black for a few minutes, because I want to be sure the focus is on the storytelling, not the shiny digital thing.

If you've got more than a handful of words on your slide, there's a huge chance you're just doing it wrong. If you've got a paragraph or more up there, you're just wasting everyone's time. Better suited as a book at that point, right?

Also, oldie but goodie. Nothing beats Norvig's rendition of the Gettysburg Address in PowerPoint:
