Power Point is for dogs and Communists. There is a much better presentation format which can be saved to a PDF, often created using a LaTeX toolbox called Beamer, but I'm not sure if the stripped-down PDF viewer on the Edge's LCD side can display these types of presentations. (Adobe Reader has no problems with them.) I'd be even more surprised if the e-ink side can display them, but I guess you can't project that anyway so it's irrelevant.
