I'm wondering how much of the strain people, especially on this forum, attribute to "backlighting" in fact comes from the generally poor ergonomics of reading on a large, stationary monitor. I definitely find it tiring to my eyes to read any lengthy text on my desktop monitor, but the same can't be said for a tablet or even my old netbook. In addition to the elements I explicitly bring into my comfort zone--brightness, text/bg colors, font size, column width--I'm unconsciously adjusting the display distance whenever I use it.
If people were reading PDFs and Word documents formatted for letter-size paper (small fonts, long lines)--pretty much the standard in "ebooks" before ereaders were widespread--well, all the worse for them.
