I chose science fiction (but really meant fantasy -- still need to get myself going this morning) as I assumed that the poll was asking for my favorite genre for e-books. When it comes to reading on my Sony, I read sci-fi/fantasy and some of the old classics that I have meant to read but never got to (like Thus Spake Zarathustra). But I really have 2 collections: e-books and p-books (hardcover only) and in p-books my favorite genres are history and biography.
I don't know how others approach reading, but I generally divide my pleasure reading day among 3 books (and spend my work day editing books, so most of my day is bookbound). I use the Sony and read scifi/fantasy on it while I exercise on my treadmill (about 90 minutes a day). In the evenings, after dinner while my wife paints (if any of you are interested in original art, I invite you to check out her website:
http://www.carolynedlund.com), I sit in my library and read a nonfiction hardcover book (currently
The Colony about the leper colony in Hawaii), generally for a couple of hours. Finally, at bedtime I tackle the third book (currently
Discovering God, which is an exploration of the concept of God -- poly- and monotheistic conceptions -- throughout the ages and various religions), which is also nonfiction hardcover, for an hour or so.
My biggest problem is that I am a book lover and buyer -- I spend a small fortune every year on books and have an enormous backlog of books to read (approximately 350 books purchased but not yet read). And when I find an author I like, I tend to search for copies of earlier works that are no longer available but are collectible. When I retire, I will have enough reading material to keep me occupied for years.
