I'm back from in Athens, we had a 2 day evangelism summit (a synod ??) followed by after 3 days of Longhorn training, and those of us who will be out talking about Windows Server "Longhorn" got to spend time with a top presentation skills coach who works a lot with our US staff. It meant listening to a lot of different presenters and seeing a lot of Powerpoint. The Longhorn stuff used the Microsoft learning templates which were familiar to me from my past life as a trainer in the 1990s; the summit slides were a bit more of a mixed bag, and one of my colleagues mailed us this the link to this page on "Presentation Zen" - which in turn has some interesting links ("How Yoda and Darth Vader would present" is well worth a look) . This video by Don McMillan is the pick of them.
