I've also heard that when you use an LCD at work, you are not staring at it consistently. You are looking around, at documents on your desk, at people who come to your desk, and so forth, and that gives your eyes chances to rest that they may not get when sitting down and reading. I think there is some truth to that. Also, my monitor is further away from my eyes than I can comfortably hold a book or ereader, so the distance may be a factor as well.
Personally, I don't have a problem reading on LCDs including my iPad but then I never have the brightness all of the way up. A properly adjusted LCD should really not be much brighter than a sheet of white paper under ambient lighting.
Of the two, I prefer the iPad simply because it means that I don't have to reach for another device when I want to do something else. The downside is that when the children are awake, I inevitably hear a chorus of "I want to play a game."
