BookBook for iPhone 5 now shipping, rear camera hole and all (hands-on). You have a modern, digital phone and reading system in your hands. If it is an IPhone 5, you are sporting a boring, antiquated user experience that looks just like it did in 2007. You crave structure and control, and you don't like learning new ways of doing things. You want your digital device to "just work", and hate surprises. Why wouldn't you want to clothe the pretty machine in a leather binding that makes it look like a Gutenberg printed first edition?
