&gt; Last time I checked, Prezi (and Powerpoint) presentations are deterministic: from the minute you hit run there&#x27;s not much you or the audience can do to change the slides.<p>I started using Prezi since soon after it came out, and this was <i>never</i> the case. You can build guided paths, though even that isn&#x27;t quite like saying &quot;run&quot;, but what was powerful with Prezi was that if you use it for content where it really makes sense, content that is inherently spatial (which isn&#x27;t actually most of the content I give in talks, so I haven&#x27;t really used it much over the years), you can rapidly move around the content, you can edit it if you want (as the tool that you use to present <i>is</i> the editor), and effectively decided how the presentation will play out as you give the talk. In this article, the talk I&#x27;m giving is done with Prezi, and while I&#x27;ve given this talk many times, I&#x27;ve never twice did I do the talk in the same order, and often decide how to order the content based on the questions and feedback I get from the audience, and no one is any the wiser as Prezi is actually really good at that.<p><a href="http:&#x2F;&#x2F;www.engadget.com&#x2F;2010&#x2F;04&#x2F;13&#x2F;360idev-saurik-on-the-mobile-application-market&#x2F;" rel="nofollow">http:&#x2F;&#x2F;www.engadget.com&#x2F;2010&#x2F;04&#x2F;13&#x2F;360idev-saurik-on-the-mob...</a>
