I think the biggest problem for me is not the formatting so much as the light. I like a bright computer screen for the contrast it can provide, but I also spend time looking away when not immediately keying something in. The result is a good balance for me.

But reading a book is another matter- the eyes tend to want to be on the page all the time. That pretty much means a regular computer screen, LCD or not, is out. And no, adjusting the brightness doesn't help much- it goes from bright and snappy to darker and murky, which bugs me just as much after an hour or two. E-book readers negate this problem somewhat but, then you have an expensive and dedicated device. The iPad may yet combine the worst of both worlds for this particular role (though it does have wider uses than the E-readers do).

So with dead trees I will stay, for now.
