Demas, I thoroughly disagree.
Dim lighting conditions are when there isn't enough light to allow the eye to easily resolve detail. That's not a problem with paper/epaper as long as you use a light source
LCD is a poor light source as it is typically too bright, and human eyes don't cope well with reading (or indeed viewing) a bright light source intently or for long periods.
The contrast on epaper is perfectly adequate and is at no practical disadvantage.
I hold that the text rendering on epaper is typically excellent and not an issue with respect to DPI. Can you tell the characters apart? Of course you can, easily. Therefore, no 'poor text rendering'. Hell, you can even increase font size with a push of a button! Try doing that with paper! Greyscale count, small manufacturing lots and 'proprietery software' are utterly irrelevant.
E-paper does
not have low refresh rate. It has
no refresh rate. It only refreshes when changing the display from one page to another. Which is good, as poor refresh rates can make viewing hard. Most modern displays do not suffer from poor refresh rate.
Human eyes *love* low detail. If we're talking about 6 pixels to describe a symbol then yeah there's a problem. But this is hardly the case.

- Human eyes get less strained when looking at poor text rendering which can occur with low DPI, small manufacturing lots, only 16 levels of grey, and proprietary software coming from consumer e-ink devices as opposed to LCD APIs for mainstream OSes (this very issue occurred with the Kindle 2, though eventually patched).
- Human eyes won't get strained by anything with a high refresh rate, including LCD... equivocated ones with poor refresh rate is like equivocating low-quality e-paper solutions like TFT with e-ink.
- Human eyes get strained with too little detail in attempting to resolve text, but neither too much nor too little detail is trouble for a versatile LCD which can use non-native resolutions.
