Query: Kindle

Being a book addict (I own more than 3,000), I have resisted electronic devices. Trying to read books on a computer tires my eyes, my neck, and back. But I love my Kindle! I can change the font size, I can hold it easily in any position, and I can slip it into a bag so that it is always with me. Now, I am never caught without something to read when I have unexpected wait times. It is a great addition to my library.
