I agree. I find that I read faster and have better reading comprehension when reading e-ink than paper, which I attribute to the fact that e-ink allows you to (almost) always choose your preferred font, margins, line spacing, and font size. Whereas with paper books, you're stuck with fonts that are either too small, or not very pleasing to the eye. It could be I'm just a picky reader, but it's rare these days for me to read on anything but e-ink.
