Hey try the Colorgraphic Voyager CF --it has an adapter for s-video, vga, rca. It comes with software that allows you to
present regular powerpoint slides. Dell sells the Margi, which you can find on ebay for $120 but it only has a VGA out.
Also the software makes you convert your PPt slides and doesn't do annimations. The plus side is the Margi has its own
power cord I believe, but with an extra Axim batery who needs it? I am buying the Colorgraphic. It is much more useful and the software is better. Don't buy the Voyager at Colorgraphic's page.. go to next tag or something.
