If you reduce the intensity of the light coming off of an LCD it can become more difficult to see the screen, and while altering the properties of home computers is not only possible, but also a good idea, this is not always the case with work computers, public computers, and other LCD screens.

The fact is that while we are constantly inundated by LCD screens in day to day life some of us prefer to take a break from all of the different light and glare levels and just relax with something that does not have as much possibility of harming the sorely abused muscles, ligaments, tendons, and nerves used to focus the eyes, and to correct our posture.

Let's also not forget one of the other advantages of e-ink: battery drain is minuscule. I love the fact that I do not have to charge up my device constantly and that if I go a few days without using it that it will still be good to go when I power it on. It was one of the big draws to e-ink devices for me.
You are right on the money. And there are size, weight and heat issues. I am using laptops, phones, and e-ink to read. I still much prefer the latter for extended use. As with all legends, there always is some truth behind it. And millions seem to agree, as e-ink sales show. Obviously not everybody is negatively affected by LCD. And yes, for e-ink you need sufficient ambient light, just as you do for a pbook. It seems to me that most people who don't like e-ink just like to read in dark places -- then it definitely is not for them.
