Obviously I haven't been understanding what you're tring to say. From your most recent comment, I think you're saying that the groundbreaking thing was showing a computer screen through an eidophor in order to demonstrate its functions live before a large audience. With this in mind, I will claim that the iPhone demonstration is similar in that it's the first case of a phone being connected to a big screen projector to demonstrate its functions live before a large audience.
