Hello Mores - I understand the need to read at night. I have used an Audiovox, iPaq, and a Treo mainly for use at night. I have also used an ebookwise reader because of the backlight. I became intrigued about an E Ink device based on the enthusiastic information found in this forum. The old Sony Credit Card offer was impossible to resist. There are a few threads that discuss night lights that work great with these devices. I too have a spouse that appreciates minimal light - this one is my current favorite -
