How I Use It
This is one product I have students review as part of an alternatives to PowerPoint course. It is however, the least favorite of the students (others being HaikuDeck, Google Slides and SlideShare).
Prezi is my least favorite of all online presentation tools. At the end of the day, it is still a linear presentation. I can do the intro and extro spective view in PowerPoint, only Prezi is much more complicated. Because of this complexity, some of the worse mistakes I have seen in presentations have been in Prezi. It seems to me when you fail, you fail big.
