Maybe he's figuring 10GB is way more than these buyers need anyway, so it will come down to ... {dramatic pause} ... form factor and battery life.

Actually, I would have to agree with that line of thinking simply based on the fact that 10GB for me is not enough for all of my mp3's and since I own a Rio central as well as an empeg I really have no reason even for the 40gig Karma. I need something SMALL with a long battery life that can hold enough music to get the yardwork done (and the rio 800 is not quite big enough even with the 32MB back pack with the 128MB). So I would probably be more inclined to buy the Nitrus then Karma or ipod based on form factor and battery life. But ONLY if it'll download directly from the Rio Central or the empeg.... if it won't do that then I'll just stick with the 800.
