Beautifully Styled Bookcases

I have a weakness for books and bookcases and as I've mentioned before here a well stocked bookcase is a must in my dream home. Even though I love nothing more than a packed bookcase full of books, I have to admit that a well styled bookcase makes me swoon. Below are some styled bookcases that may not be entirely practical but are definitely pretty! Which do you prefer, pretty or practical?
