Four years ago, I bought a book entitled, "Mac OSX: The Missing Manual" and noticed it had reached the #1 best sellers slot at Amazon. I remember wondering how an operating system with 3% of the PC Desktop market could sell enough books to rank #1. Then, I realized there I was buying one too. I didn't use a Mac, but my wife bought one and needed to learn this new fangled UNIX desktop. The point? The Missing Manual served a big need - big enough to warrant a #1 best seller.
