I'm an old timer. I remember a time before PowerPoint existed - and we did communicate with reports, whiteboard, flip-charts, and talks. Trust me - PowerPoint is better.

If nothing else, if forced people to put more thought into their talk - since they had to write down something on those slides. And it allowed for the potential to create something persuasive with graphs and sequence to accompany a talk. That really didn't exist.

And use a Word Processor for talks? I've done that - it can be done, but it doesn't compare to a specialized tool you can use to put together a slide set in a matter of minutes.
