Last year I bought a Samsung Galaxy tablet and downloaded a Kindle app for it.....geez, that makes me sound as though I know what I'm doing, doesn't it? when really I don't have a clue, you know....because in November I had shoulder surgery and knew from previous experience that holding a regular book would be painful. I also bought a Book Seat for almost hands-free reading. I read for a while before going to bed, and it doesn't keep me awake - but on the other hand I don't like the green light from the bedside clock, and if I had my way it would go. I like my sleeping room to be dark, really dark.
