I have Macular Degeneration and since I received my Kindle 2 I have not put it down. It was very difficult for me to read anything unless it was in x-large type. My Kindle is great because of the ability to change font sizes. I am now reading
"Wepons of Choice (Axis of time book 1)" by John Birmingham. Great read, holds my intrest very well.
I wish you all the best!
