When you're not in a room, turn out the light! Same should apply to the Kindle.<br /><br />When you turn the backlight down to ZERO on the kindle paperwhile, there is still a degree of backlight being emitted from the device. Try it. Go into a dark room, turn the kindle's backlight down to the lowest possible setting, and you'll see that there is still a glow emitted from the device. The problem is that 99% of the time I, and probably most kindle paperwhite users, am reading in sufficient light and therefore don't need the backlight on. I know. I know. It's only a little bit of light and it only uses a little bit of battery, but it just doesn't make sense. If we don't need to be using the light, let us turn it off! Trust your users/customers!<br /><br />Amazon should update the software so that a setting of zero on the kindle paperwhite's backlight completely turns it off. Otherwise it's just wasteful. I'll change my review once this change has been made.<br /><br />And for those who are rarely reading in the dark, choose the regular kindle until this has been fixed. Annoying.
