I didn't vote because it's either or and I don't agree with that. For years I've used an eInk device to read. For the majority of my reading it was perfect. However reading at night was a pain. I tried many different lights but the glare on the screen was too much. I was one of those fools that dropped down $70 dollars on SONY's light because it was too the best solution. Unfortunately my SONY broke and it was replaced with a k2. So I was back in the same boat.
The solution was to start reading on my phone and wispersync was awesome for keeping my kindle and phone synced.
Point is my eyes never strained, no headaches, eye pains. Reading was optimal in each situation. And with a good reading app like Moon one can pick any color and drop the brightness as low as one wishes.
I will note one instance where eInk is easier on my eye than an LCD screen. If I try to read an LCD/LED when I've just gotten up I have a harder time focusing on the page it takes me about 1 min to adjust my eyes while the eInk takes no time.
