Just an update on my 97 year old mother's introduction to the Kindle. After she enjoyed reading a book on a borrowed Kindle, I bought her a Kindle 3G(keyboard model) with a cover that has a light. Although an older model, I prefer being able to page with buttons and I felt that would be easier for her than a touch screen as she has never used a touch screen. She retired before computers. For Mom, the next big thing was the electric typewriter.
She has had no problems with the Kindle and is reading Robert Caro's first book on Johnson. This book would be too heavy for her to read a printed copy. She moved to the Kindle because her eyesight is poor and printed books were just too difficult to read. Now she can scale the type, has a restful background, standard typeface and a book that is not heavy. I found the Kindle a real boon following my cataract surgery when my eyesight changed every day for awhile.
It is a real shame that older readers don't consider the Kindle because they see it as giving up books. In fact the Kindle is ideally suited for the older reader.
