I refused to do flight briefs off PowerPoint and would only use it to display maps or imagery as the need arose. I hate PPT with the fire of a thousand suns, and after working in a job at regiment, I'm fully convinced that we spend more time putting the PPT of the plan together than we do thinking through the plan itself. People would spend hours getting video or sound or moving icons to work right, rather than polishing the content of the brief.
White boards, dry erase markers, and briefing from memory. Learn it, live it, be more knowledgeable for it.
