I'm a business geek, I guess, in that my first reaction to the iPod Photo wasn't, "Cool, I can transport photographs!" Rather, "Hey, I can do PowerPoint/Keynote presentations without a laptop."

You won't be able to do fancy transitions--at least you won't be able to program them individually--in an iPod Photo slide show, but you can use PowerPoint or Keynote to export individual slides at high-resolution, load them up, and look like a very modern person indeed with your slick presentation tool.

If you think this is unlikely, remember Adam Engst's remarkable on-the-fly PowerShot conversion when a projector failed to materialize for a presentation.

Some handheld organizers and even stand-alone digital video projectors can play back PowerPoint stacks. Apple could conceivably add flavors of playback in future versions that would allow multimedia inclusion without going to full-bore video.
