Join Me in Discovering PowerPoint 2007

I've caught up on my sleep and appear to be a glutton for punishment again. I have been asked to co-author a new book on PowerPoint (more details soon). Essentially, I will be putting together a new book on design principles and techniques for effective screen graphics. The book is going to focus on all versions of PowerPoint, including the recently announced PowerPoint 2007. I am starting to wade into this latest version (its a public beta). If you are a cutting-edge, risk taking technocrat, feel free to join me. You can download the beta (legally) from Microsoft by clicking here. It's a Windows only program (though its running just fine on both my MacBook and MacBook Pro). I welcome your comments as I work on the new book. Requests and suggestions are welcome.
