Thanks a lot Arwen for the pointers.
I will wait till end of March, since I'm moving out of Berlin and then I will get a PineNote.
I'm interested to see if I can help with the eink part and also make it available to use alternative eink displays. This epaper I was mentioning has 2232x1680 resolution but I think since has a color filter on top, the real resolution with color is 3x smaller. (Same happens with the eink.com Kaleido displays)
What I still do not understand is how they make full black. But I guess independentaly if the color filter on top is Red, Green or Blue if you cover all the pixel with black, then you will see black
But still does not click on my head how they do the grays. I guess big part is played by the software controller and the epaper is just a normal 16 grayscale matrix where the hardware is not aware that has a color filter on top, and the rest is done by controlling it with the right driver.
