Rationally speaking, there should be absolutely no difference between reading from an eInk screen or reading from a backlit screen whose brightness is correctly set.
I can only think that people who complain that they can't use backlit screens perhaps have the brightness set too high?

I don't have a problem reading backlit screens per se -- I actually have a Kindle Fire which I use for magazines and comic books. But it's just over an extended period I feel drained by the bright screen. I also like to read under a bright lamp, or better yet, out in the sun, and the LCD screens tend not to work as well in that context. I haven't tried reading on an iPad 3 so it may be better.
