As much as I adore and will always buy real, physical books, I do most of my actual reading on my Kindle, where I can blow up the text to a size I can read. I need a magnifying glass to read real books, and while I do it for research and gleaning information from nonfiction books, Kindle has given me back my multiple-books-at-a-time reading habit.
I've re-read many of the classics through free downloads. My only problem with many of the freebie sites is they include a predominance of poorly written junk books. I love good contemporary literary fiction, but the really good stuff is rarely free. These lists will often have a category for literary fiction, but their definition seems to be merely books that use unusual or long words, not excellent writing. I'm fine paying for good writing, as I like to support these writers.
