I didn't want an ereader since I was used to getting my books for free at the library or cheap at thrift stores. When I could only read large print, and then still got headaches, I began to think about an ereader.
Now headaches and print size are never a problem. My arthritic hands no longer suffer holding books. I can get more free or cheap books than I imagined, but I love my readers so much that I spend much more on books than ever before. I can travel with an entire library.
