the iPod Photo is a good idea that they really left crippled and incomplete and, therefore, relatively useless.

Nikon announced the
CoolWalker over a year ago, but there's still nothing you can touch or buy. It looks like it will be a good option, but no price announced and they're only talking about a 30MB HD, by the time they get that out, for the price they'll probably sell at, it should be a minimum of 40MB, and 60 would be a lot better. For now, however, it's just etherware.
I also heard word of another, similar, image storage device but with a much larger screen (and much higher price), but now can't recall where I heard it, who made it or any details.
