How to demo stuff to people where a sense of how it works is evident and you get a sense of being taken through a journey. Tell it like a story as it is told means you are no longer the guy who is shown how the stuff works but almost get to experience what it means to own or work with that product / tech stuff or gadget. There are many books being written on this topic such as slideology, presentation patterns and effective presentations and so on. Each of them giving you on what is needed to convey your essence to the consumer of your talk. There is a great deal of learning that Steve Jobs added to this topic and many refer to him as the epitome of someone who told a story and that too a captivating one. No one presented like Steve was the standard. Men of his caliber apart from marketing apple to the world around did in many ways up the standard for presentations and cut down on all the flab that goes with presentations. Carry with you the item that you are going to demo , build a story around it weave it together and the world is the stage for the actor/presenter.
