I wish E-Ink would get more attention because of this. Forget power consumption as the killer feature...it would look more natural and you wouldn't be shining a bright light in your face all the time.
I'm pretty sure a generation from now kids will not be able to comprehend that we once used additive light displays. It's really a poor reflection on the way markets work that the "good enough" of backlit displays has stifled the correct way to do it for so long.
