<p>Many excellent points are made in the above responses. I suggest another point of view that may be important. It might be that at some point you will work in industry. I've found that PowerPoint is often the preferred mode of presentation. It is useful for everyone to learn how to use this medium if only because it may facilitate working with certain groups - industry.</p> <p>For myself, I like the flexibility and simplicity of a blackboard.</p> <p>Suggestion for whiteboard users - if you find a "dry" pen, throw it away! All to often, I see someone discover that a pen doesn't write, put the cap back on, and return it to the tray. Tossing it out would be helpful.</p> <p>Final comments: </p> <p>Edward R Tufte Dr. Tufte, in my opinion, dislikes any PowerPoint presentation. The information desensity is just too restricted. See his web site www.edwardtufte.com/tufte</p> <p>Gapminder There are some amazing examples of what can be done with a flexible electronic media in presentating data. See www.gapminder.org</p>
