This article, on the cover of today's New York Times, speaks directly to Christine Rosen's issues with PowerPoint - the shorthand it necessitates can often create issues on a macro scale. The image below, taken from a real military PowerPoint presentation, seeks to "portray the complexity of the American strategy in Afghanistan," and the Times notes that it "certainly succeeded in that aim."
I hope Rosen's article did not bias you too much against powerpoint presentations since they can be very valuable, too.
