I’ve said before: if you wanto to dazzle with your presentation, use Prezi. The Prezi team did to presentations what Google did to email: throw away all pre-existing notions, re-think why and how we use email (presentations) and build something from scratch. That’s how you get results that truly dazzle.
Of course that brings up the question of just how much you want to dazzle: probably not too much in the corporate world: as Prezi throws away all notions of what presentations are (used to be), there would be too much “undoing”, too steep a learning curve. PowerPoint and Enterprise are too deeply intertwined. That said Prezi is a great tool (online and offline) for superstar freelancers, small groups, or just about anyone who gets on stage and wants to … yes, dazzle.
But Prezi can make you dizzy 🙂 at least in the video below, played 10 times the original speed. So hold on to your chair tight, and enjoy…

Hi, thanks for this nice post. Please allow me to add 3 facts that prove you can actually create a better presentation with Prezi beyond looking revolutionary and new:
1. With Prezi you can see the big picture and the details easily, so you can make sure that the content of your presentation makes sense.
2. Prezi’s spatial layout help you to convey message better, since our brain is wired to think large spaces rather then slides.
3. As a presenter, you can avoid long boring monologues (death by bullet points), and encourage audience involvement by moving across the canvas.
These are the most important advantages of using Prezi instead of slide tools.
I just wish that people would use the rotation much less as it rarely leverage communication. But I reckon that people always have to push the limits to the xtremes. I agree with @Zoli on the first 2 points while point three has nothing to to with the tool but how you choose to present. One thing I don’t like about Prezi is the bad support for rich media, which is the primary reason I’ve started using http://www.AHead.com instead (+ 3GB free storage).
