That's a really good list, and I think the Ipod covers almost all the bases. But for me the camera download feature seems more like a gimmick than something I'd actually use. My iBook and its Crumpler bag is tiny and weighs bugger all so I'd probably just carry that around... and to be honest from a data integrity point of view I'd trust CF over a miniature HD any day.

The only other thing is the car docking, every ipod solution I've seen has been a piss-poor waste of space compared to just using an aux-in lead.

EDIT: and every ipod case I've seen still leaves the jog wheel unprotected, probably the only bit I'd really want I'd want to protect.
