My eyesight has gotten worse and I can't read a typical book with its tiny print. The biggest Pro for me is adjustable font sizes. Another Pro is free books! After purchasing probably a 1000 books in my life; I'm done buying and storing books. I did the library thing for a few years when the library was only a couple of blocks away but book selection and availability was never good. Now I can easily get any book I want from the comfort of my home.
