There is quite a bit of variation between EInk screens even on the same kind of device. The Sony and Kindle probably are using the same screen (both from PVI), and they are using the same controller. I'm not sure why Sony did not upgrade from 8 to 16 grey levels on the PRS-700. It seems likely that all future devices using the Epson controller will have 16 grey levels. The controller on the Kindle 1 only supported 4 grey levels, so 8 or 16 was not an option for it.
