Thanks for sharing! I too have looked at the Palma, but without it also being a phone, I can't go for it, because I'd have to carry it and a LCD-screen phone.
Colour e-ink works by having a colour filter over the screen, and every third pixel being dedicated to each colour (please correct me, people who actually know the details!).
Therefore they inherently have lower resolution, and are also by nature around 2/3 less white in the pixels not displaying anything.
When reading text, most pixels are uncoloured, meaning in most cases you significantly lose screen resolution, compared to b/w e-ink.
Thus, with colour e-ink screens, unless you're out in sunlight, you'll need backlight most of the time.
This is my reason to keep using the black and white versions, and it might be something for you to keep in mind when you select your next reading device.
