Prezi - The Zooming Presentation Editor

I've seen Prezi used subtly to great effect, but I've also seen it abused where complex transformations are used for what really should have just been plain text.
Where it works is where you have a true overall structure (such as a map or blueprint or the object you are talking about) that actually represents your presentation, and isn't just some abstract pattern you've decided to shape your text around. For example a presentation on a new model of car where the overall structure is the drawing of the car and the Prezi moves around and zooms in as you discuss individual parts.
On the plus side, you can build very quickly once you get the hang of it and not get sidetracked with a lot of formatting options. It's also nice to be able to flip to a non-linear mode where you can just click to whatever it is you want to talk about and not flip back through your slides. The zooming provides for very simple hiding and emphasis of points, including "hiding" extra content for future sharing (eg, embedding).
The big downside is you have to be really careful with the panning and zooming. What seems like 'just a little' when your building can easily feel like an amusement park ride when it's on a big screen. Also, you can't upload to slideshare unless you record it as a video first.
Overall, we were very happy with it, and the audience seemed to enjoy it. But you definitely want to build some practice Prezi's before doing the real thing. We found it very useful, but it has the potential to be very distracting if you aren't careful.
To me the difference seems to be that CS people are more aware of current technical possibilities, and take a "we've been there before" attitude. To humanities people, it's all new and spectacular. And who doesn't want to impress their peers?
As someone who works on the border between both fields, I can only hope this soon blows over. It tends to be overused and annoying, though I can see it as beneficial in non-academic fields.
(I don't even really mean that negatively; my own computing style tends towards CLI, and/or "weird" window managers like dwm.)
One tip: go very easy on the movement - you'll make your audience sea sick!
