Slide Show Duo

PowerPoint is a very commonly used presentation tool that provides a series of single slides, to display information and images. Its disadvantage is that only one slide is displayed at a time. Slide Show Duo is an add-on for PowerPoint that allows two slides to be displayed at once. The add-on includes extra animations for how two slides interact with one another.

An easy to install, but difficult to find addition to Microsoft PowerPoint

The application does not require any special effort to install and, as long as users have a version of Microsoft PowerPoint installed, the add-on will be set up and activated automatically. However, once the app is installed, it can be quite difficult to actually use it, the button to start it is lost among the standard PowerPoint buttons.
Fortunately, the application's website includes tutorial documentation to help users locate the button and set up the add-on. Once users find the button, the add-on is quite easy to run. It displays the number of monitors and slides selected and informs users how it will display them, then the presentation begins as a regular PowerPoint presentation would.

A useful tool and one that clearly improves how PowerPoint operates

It would be easy for the application to simply display two slides at once and nothing more. Instead, the application includes a novel animation system for how the two slides interact and work together. When the presentation starts, only one slide is present, then the second slide appears by pushing against the other and making room.
The slides push against each other every time one is replaced, until only the last slide is left. The approach taken by the add-on makes sure that a presentation displays a clear start and end, yet the rest of the presentation takes advantage of multiple slides. This attention to detail ensures that the application only enhances, rather than compromises a presentation.
The extra feature this application provides comes at a significant price, the extra cost might not be worth it for several users. Given the limited addition it makes to PowerPoint, many users will have a hard time justifying the expensive add-on.

An interesting way to boost PowerPoint presentations, but an question balance of value and use

Slide Show Duo clearly adds a new and interesting feature to PowerPoint presentations, yet it is hard to balance that with just how much it costs. It essentially adds one extra feature with a price tag that could easily fit an entire application, just not an improvement on an existing one. Users will have to think carefully on just how much they want it, but, for those who do purchase Slide Show Duo, there is no denying that it is useful.
