To use Impatica ShowMate, you'll need a BlackBerry software version 3.8 or later.

From a Palm Treo

The Palm OS enjoys a wide variety of third-party applications for PowerPoint conversion, viewing and presenting. Some of the better PowerPoint applications are office suites that do other things besides power your presentations. The best of these include the $39.95 QuickOffice and the $49.99 Documents to Go (Note: Don't buy the "Standard Edition" of Documents to Go -- it doesn't include PowerPoint support).

The $29.95 RepliGo converts office documents, including PowerPoint, for use on a wide variety of mobile devices, including Treos.

On the hardware side, one nice solution for Treo 650 and Treo 700p owners is the $279.99 iGo Pitch Duo. This innovative unit actually uses a Pentium-class chip to speed up your transitions. It plugs into a projector with a VGA port. Your Treo communicates with it via Bluetooth or your Treo's USB connector. Just plug it into the projector, and both view and control the slides on your Treo.
