And when those young folks get to be old folks what is their eyesight going to be? It isn't just because what you are used to, the e-ink and using light is easier on the eyes.
With a backlight screen you are staring into a light.

Note, there are few super glossy e-ink displays. Nor are most books printed on extra deluxe glossy paper.
Sure, you can read off of a screen. What are the long term effects though?
I'd like to see a Poll with Honest feedback from the users of Kindle and like E-Readers asking us how much time do you spend reading on your reader verses how much time do you read on your computer?
In my case and I own a Kindle, I have say that I may spend 1 - 2 hours a day on the average reading an ebook on my Kindle and a hell of a lot more time each day reading web content etc on my computer.
So to me I see no great advantage eye strain wise whether IM using an E-ink or lcd display and my eye sight is not 20/20.
The only advantage I see is the battery life and the kindle lasts forever compared to an LCD screen device.
However, I would settle for more frequent charging IF I could have a large enough device that displays in color and proper format when I read newspapers, magazines etc... Most ebooks are in black and white but I would love the color for books that contain pictures etc....
