This, IMHO, would be the cats a**.
They make a function on the iPod where you can actually view a list of data files. So, yea. there you have it. you can scroll through all of the data on your lil' guy.
So whats next you say? Ok. Apple gives us media readers. cf, smartmedia, mm card to firewire.
You plug the reader into the ipod (i'm seeing something like the Zio reader....no cable) and us digital photographers can pop our ipods in our pockets and start shooting.
Fill up the card? Just plug in the cf reader, scroll to you "pics" folder and press a button on the reader that transfers the pics to the folder.
And you can keep the music playing while transferring
As it stands now, I'm content(-ish) with carrying the Minolta DiMage 7i (a fairly largish camera....), an external flash unit, four cf cards, filters, tibook, pcmcia card reader, etc.
just mo $.02
