There is nothing wrong with Prezi if it is used right:
- Use zooming effects to support your story: zoom in on a technical diagram for example, hop in and out of a time sequence, focus on parts of your product, highlight different areas of a map. Zooming for the sake of zooming is not helping anyone.
- If you are in a small meeting, leverage the non-linear navigation to have a good interactive discussion. Random story sequence shifts for a big audience makes everyone miss the plot.
