What does it mean to "present naked" (with technology) to you? Love to hear what naked means to you?

I am in the middle of writing a book (out later this year) on the art of delivery (Called The Naked Presenter). PZ was a sort of introduction and PZD went deeper a bit into just design. Restraint and Simplicity were the keys. In Delivery these are important too, but SHIZEN (自然) or naturalness is my focus here. Of course, "going natural" or "totally naked" could mean nothing but you and the audience (no slides, visuals, nothing). That's certainly naked too. But my focus is on how to present *with* technology (ppt, key, prezi, video, etc.) and yet do so in the most naked way possible. So I am curious about two things here. (1) What does going naked mean to you? And (2) what today are one-two things that you find are still common mistakes made when it comes to delivery? (These could even be kind of pet-peeves if you like).

I greatly appreciate your comments and/or stories (and I am sure other readers will as well). Thanks very much!
