Guido,
My presentation was mostly showing the different layers I add to Illustrator, in the order I do it. There wasn't a lot of time, so it was a very brief presentation. And, without Illustrator, you couldn't open the main feature of the presentation.
I like Illustrator for many reasons. I wish I had a true "presentation", but without someone having Illustrator, a presentation may not be worth much. It is a hands-on learning experience.
