Dear Henrycat,
Thanks for all the information you have posted already. I am trying to learn which of the e-ink readers might work well for scientific papers - I hate carrying around lots of these, and killing trees to do so, when I could put a few hundred on one of these, and read them anywhere.
Could I impose on you to try one on the Iliad? I am curious to see how they are rendered, and how readable the figures and columns etc are.
Here is a link to an open access pdf of a typical paper:

Would you be kind enough to load it onto the Iliad and give me your impression?

Can the grayscale figs still be made out. How readable is the paper if it is all on one page?
Thanks!
Oliver
