my contrast is set a little higher than yours, but brightness is about the same. i have tried to turn the backlight off altogether, but it lost too much legibility, and between reflections and loss of detail when i turned up the contrast to compensate it was easier just to keep a minimum of backlight. especially since, as regards "careful angling", i read in all kinds of crazy positions ! so the fewer "angle" constraints, the better.

Contrarily, I find it cozy to read in the dark, without having to waste power on room lights.

i have the impression that a lot of people do ; i find it really suprising, because especially if my eyes are *already* tired (as they usually are, at the end of the day), it can be physically painful to me to do this. i must have defective eyes.

The OLPC screen is the one in the One Laptop Per Child computer. At 4.5x6.0 inches it can fit a slighty-wider ETI-2 unit, and at 200 dpi it's sharper than any e-ink screen. People who've seen both say that in purely reflective mode OLPC looks better, both for its sharper letters and its whiter background. E-ink is good for two things: purely reflective viewing and low-power. OLPC isn't as low power, but it does reflective more sharply and can do color, which seems a better combo to me. Pixel Qi plans on commercializing the OLPC screen soon.

i didn't recognize the acronym but i thought that must be what you were talking about. i would like to see one of these screens in person ; they sound really interesting. according to the article you linked, the color display still could stand to be improved for text / straight lines etc. but for concept and price it seems pretty amazing... and defnitely a big leap forward in display technology. i can't wait to see what the 2nd generation will do...
