My dear husband gave me an e-reader, the Nook, for Christmas. I really like it. It allows me take loads of books along wherever I go, without hurting my back.
It also, and it pains me to say this, allows me to change the size of the text so I can have a "large print edition" anytime.
And it's almost as cozy in a corner of the family room as a paper and glue version.
