The iPad is a well-designed gadget, to be sure, but it doesn't really look classic. If you want it to fit in in your old-timey library, for example, it won't really fit in. But it would fit in just fine if you used a BookBook case.
TwelveSouth's BookBook cases are beautiful leatherbound cases for the iPad that are designed to look like old hardcover books. They'd fit right in on a bookshelf in your library with the big globe and crystal scotch bottles. Every one of them is handcrafted and unique, justifying the relatively high $70 price tag.
