I'm excited about what I've seen so far of pptPlex, Microsoft's new add-on to the popular PowerPoint presentation software. The application adds interactivity to presentations, allowing users to "zoom" in and out of content, and permitting them (and audiences) simultaneously to view both parts and the whole of a presentation, via the "ribbon" interface. This may be familiar to Mac users, but it's new for PowerPoint, which I've always thought seemed just a teensy bit stuck in "80s corporate" mode, suffering in comparison to, for example, Apple's Keynote. A product of the OfficeLabs initiative, pptPlex could help Microsoft to break away from that outdated image - you can even navigate it using a Wii controller.
