Well, the whole reason that e-ink was developed is because backlit screens strain your eyes, that's a fact. And if you're a devoted reader, the advantages of e-ink over an LCD are obvious. Your saying that the back light makes the iPad a better reader tells me that you are not exactly a bookworm... If you read a few pages of a book every once in a while, you're not going to notice the difference, but try reading for a couple of hours or more _every_ day and see what your eyes think of that. Browsing the Internet on a backlit screen, even for a few hours, is not such a big problem, since normally your eyes are jumping from one place to another, skimming, and they're not fixed on a single thing for long periods of time. But a book is a whole different experience.
