Wouldn't you think anyone would simply adjust the brightness down on the Kobo Glo if they felt it too bright and regard a greater range of brightness as a plus? Talk about biased reviewers... or at the least idiots.
More importantly why didn't they adjust the brightness on any of the units? Perhaps the Kindle does not look so great or evenly lit at lower than max power?
With all the talk of blueness, it makes me wonder if the next innovation will be offering warm white LEDs or RGB units so you pick your own color mix for the background? Might be nice with a light red background to preserve night vision...
