Who reads books in America, and how?

Most of the ebooks I read are free, public domain works where there is no reason to buy a physical copy. I already have about 1,500 paper books, my new purchases are about half paper half electronic.

@Daedalus: There are a lot of good fantasy and sci fi books, even series, out there as well. The good ones tend to border on philosophy. Like any fiction, they can explore all the major themes of life, only in their case, with some of the constraints removed.
