No one has pointed out that, even with the shorter battery time, it still fills the time. I've filled the infrequent dead time with "what do you have on yours?" conversations with other iPod users.
There doesn't seem to be a sense of community with other players--and I used to carry a Nomad Jukebox, a Rio 600 and a 300, so I'd know.
Also, I always bring my laptop with me and, when in C or F, the first thing I normally do is plug my Kensington brick into the seat, plug the firewire cable into the Powerbook and listen to it through my PowerBook during a rather violent game of Civilization 3.
