Presenting from any mobile device involves three parts: conversion of PowerPoint slides, displaying the converted slides and connecting the gadget to a projector.

Any iPod with a color screen can be used as a presentation device. But first you need the right software.

A $20.95 product called ThinkFree Office 3 Show, iPod Edition, lets you create, edit, convert and store your presentations on your iPod. The conversion process saves each PowerPoint slide as a .JPEG image. To present, you scroll through those .JPEGs using the normal photo viewing function of your iPod (choose Photos, then Slideshow Settings).

A $17.95 software application called iPresent It converts PowerPoint slides to iPod-displayable images. (If you have a Mac and convert from Apple's Keynote software, rather than PowerPoint, the software will even preserve your builds and transitions.)

Another app, the $14.95 iPodSync, is designed to synchronize your iPod with Microsoft Outlook, turning your iPod into a PDA. A free download for iPodSync users called PowerPoint Exporter batch-converts PowerPoint slides into .JPEGs for presenting.
