What puzzles me is that in bright rooms (e.g., all my daytime reading if the window blinds are open) I turn the light all the way off . One of the points of eInk is that you don't need any extra light when you are in a bright room.
Why does Amazon want me to turn the light up, which eats up the battery? I realize it does make the screen look whiter to have the light on in a bright room, but as far as I can see it does not make a noticeable difference in readability.
The new high end eInk Kindle features automatic light adjustment based on a light sensor. If that means that in bright rooms it is going to crank up the light, I would not be happy. Does it do that? If so, can it be overridden?
 well, not quite...the light cannot be turned all the way off on the Paperwhite while reading. It only goes all the way off when you put it to sleep.
It's actually easier on your eyes.

Amazon also says that you can fine tune the behavior if you don't like the default.
