Pros: The most obvious advantage of Prezi is its novelty. Instead of presenting content one slide at a time, Prezi lets you zoom out to see the big picture and zoom in to examine supporting details. This is accomplished using frames instead of slides.
Cons: The cons of Prezi is that your presentation can easily feel unstructured. If too much zooming and panning are used your audience can feel dizzy and a bit nauseous. It can be a bit gimmicky and unprofessional.
