DR Jane -
I got my Amazon Kindle [electronic book reader] a little over a year ago, and I can truly say that I love it more than any other electronic gadget in my recent memory. It doesn't need to be any wider. You soon lose the sense that you're using a gadget; it becomes just like reading a real book. One note of caution about your post, however: the e-ink technology is great for reading in sunlight or indoors, but it is not backlit, so at night in bed if there are no other lights on in the room, you would still need a booklight.
