As far as 16 vs 8 greyscale, I asked enTourage a while before release about a 16 version and they told me they could not get the screens, which was why they went with 8. Now, I don't know if they couldn't get the 16 screen for a certain cost or other requirement, since they were advertising the price. But it seems the screen is only 8 greyscale.
