BookApp of the Week: iBooks

I have iBooks, but I don't use it as much as Kindle, simply because all my books are on Kindle. One feature that I really like about iBooks is the fact that when the room is dark the screen switches colors so that the words are white on a black background. It helps save the eyes. You can sort books by recent, title, author, or categories. And it's free, so that's not nothin'...
