Prezi - I don't get it

I've talked about this on Twitter, but maybe a reader can help me come to terms with Prezi. I don't get it.

I recently saw another person who used Prezi for the presentation, and again I thought, "This is everything that we complained about with Powerpoint. Needless, distracting animations. The only thing missing were sound effects, and I could imagine them containing whooshing sounds and spinner sounds and ratchet sounds to fit the nauseating motions.

Seriously, if Microsoft ever decided to steal .. sorry.. build similar visual effects, wouldn't we immediately begin to complain about them?

Or am I missing something? Am I allowing my stomach queasiness when I watch the zooming and spinning, etc, to cloud my judgment?
