The sort of ereader that I really want is... A BOOK!

Joke aside, the more an ereader will resemble a book, the better it gets.
That's a shame technology has evolved abandoning the enormous advantages that were obtained by centuries of work on book/paper crafting.

what I want so :
- multiple eink page reader. Up to now 300 pages would be enormously expensive (I don't know how much, maybe 300*$200). That's the best way our brain can peruse through information, by using a spatial reference.
-flexible paper would be better of course if it's a multi-page ereader.
-Color! so much work has been done on the dead tree paper technology to get crisp colors, let's put it inside eink.

Maybe one day eink technology will even supersede LCD/LED technology. Heavy blue light emissions, energy consumption even when still images. That should go to the trash rapidly...
