I got the Little Black Book. Similar, but different. I originally thought I wouldn't use it long, but I still love it for every day. It is a little bulky, but worth it. And unlike the Bookbook, it has a camera hole.
The camera hole is what would kill the BookBook for me. I can only wonder why they would have left out the hole for the camera.
Thanks for the Little Black Book link. Going to check it out.
