All I want to do is comfortably read PDFs on a screen that is not backlit. I'm looking into it and this marketplace is garbage. Any device relevant to my interest appears to be a $700+ gizmo that does a million things I don't need. Maybe I'm not appreciating the intricacy of e-ink technology, but it seems a bit steep just to read e-books without straining my eyes against a monitor. Am I shit out of luck?
