I think it would be great if apple made a iPhoto version for the iPod so that when you are out and about you can hook up your digital camera and unload it to your iPod, this would be so much better than dealing with memory cards.
yeah, EVERYONE's had this idea, and apparently everyone feels the need to post it, without searching for other threads (there are several in my recent memory alone).
It's also been suggested that Apple may update the iPod software to allow you to use your iSight with iPod for image capture. If it happens, I wouldn't be surprised if you can only use this feature with an iSight, at least initially.
