I agree, I think it's worth going for the 64GB especially if you plan to stick with this device for a long while (as I do - hopefully until a similar device is made)

There are numerous sites selling 64GB cyan and magenta but I'm skeptical it's the real thing.
So from those who have bought or who know first-hand, do any coloured models exist in 64GB yet?

Also, does anyone know if the White model is just coated or is it actually the material? In other words if it gets scratched it would be a disaster if the next layer colour was exposed.
