1 year, 4 months ago: Powerpoint has been dominating the presentation sphere ever since real slides went out of fashion. It’s a great tool, easy to use, and part of the Office suite. So basically, it’s the mainstream go-to presentation application.
In the past two years, though, I have noticed more and more speakers using Prezi for their presentation. As one panelist once told me, “it’s like Powerpoint, but on steroids!”. I actually used Prezi for a keynote I gave in November, and it really wowed the audience – OK, it wasn’t just the presentation but also its content too 
What’s your take, Powerpoint or Prezi? Which do you prefer and why? Any other hidden gem out there we should be aware of that is even better than these two?
