I'm a sucker for books. Doubly for anything that makes things that aren't books look like books. Especially when those things that aren't books but look like books are super tiny and adorable. Enter: BookBook for iPhone 4.
The BookBook line of leather-bound cases has already graced the MacBook and the iPad, so it was perhaps inevitable that it would end up gracing Apple's slim smartphone, too. Better still, it doubles up as a wallet. An adorable, $60, leather-bound wallet that looks like a 17th century Zagat guide. [TwelveSouth via CoolMaterial]
