Well the response from my players has been outstanding. My niece caught a glimpse of the PowerPoint (I had eMailed it to my brother as he is one of my players) and thought she was watching a movie at first. She was so impressed she came by just to watch us play a session.This is really a great idea. It's a shame I'm not a DM, but I'll see if the DM could use this technique.
I think it is a good medium to introduce all kinds of new content (e.g. background material, story arcs, etc.). I made a small one (only 3 slides) for an adventure in my Dawnchaser Trilogy campaign (each of my campaigns are Trilogies...one for each tier of play).
