This is not entirely accurate. On the PW the light guide directs the light at the page - where black e-ink particles will reflect less light than non-black will. Especially so since the light is so close to the screen.

I can confirm the "flash bulb" effect on my new PW2 - and it is much more distinct than with a light-covered $69 Kindle, where the light is higher up and its effect on the surroundings is much more constant and not dependent so much on what the screen displays. I tried side by side in a dark room and PW2 has the flash bulb effect and $69 Kindle does not nearly as much. More experiences on that when I get some time with the device.

Of course the flash bulb effect is less the less the PW light is set at. If you read with very low light, there is less to flash.

p.s. I agree lighted covers can disturb partners more then a PW. My point was simply to separate e-ink issues from frontlit e-ink issues, when sometimes people in my opinion seem to confuse them too liberally.
