I tried Prezi yesterday, and looked at some of the presentations others made with it. It’s a nice idea, but absolutely not the presentation tool i’m looking for. Prezi basically is a mind-mapping tool, with some nice transitions. But mindmaps are for brainstorming your presentation content. You do not create a compelling presentation by showing a mindmap.
Slides need to be visual support for your story. It should be about visual storytelling. A presentation needs to be more like a live spoken documentary on Discovery channel or National Geographic Channel. I want to be able to create a movie with a presentation tool, not embed a movie. After you create the mindmap of your contents, you need to visualize it. This is where prezi falls short.
In my opinion it should offer a way to translate your mindmap into a storyboard. I really want a presentation tool which allows me to sketch out all the slides on a storyboard using a Wacom tablet. After you’ve created the storyboard, you need to fill the slides with all the real images and graphics. This means the software should have a lot of support for creating (vector) images, and adding photo’s. Integrated internet image search would be perfect. This means it needs to be a combination of animation software with onion skinning support, e.g. Pencil, vector graphics, e.g. Adobe Illustrator or Inkscape, and something like flickr search tool compflight.
