Just wanted to say I enjoyed this article a lot. I just got the 40G iPod Photo last week because it got so much cheaper (relatively speaking, anyway $). This article (and the companion eDoc which i bought) are exactly the kinds of things I like to see more of.
Also, I'd like to second the request for getting some sort of a "sync" tool that will synchronize my audio and video slideshow. I've seen similar functionality with training-focused products like Camtasia Studio, and Lectora, and of course, Flash, but I think these are overkill for making a quickie show to throw on your iPod and show the family. Thoughts?
