Here are a couple of quick tips for those of you doing demos and generating excitement about your products, which many of us at Microsoft do, or at least try to do :-) 

1. A book by Peter E. Cohan: Great Demo: How to Create and Execute Stunning Software Demonstrations
2. Guy Kawasaki's Top 10 Rules for Evangelism as transcribed by Paul Williams.

This is in addition to my Good Demo Tips entry back in January 2005.
