Presentation Zen - Garr Reynolds

This book is fantastic. Quick, easy, inexpensive, must read! It doesn't matter if you are presenting at the office, school, or some sort of user group. There is a bit of focus on technical presentations, but the ideas are good for all types. My slide decks go better after reading the first 2 chapters, and I witnessed the same results for friends.
