I've just ordered it too. I think there's a lot of interesting information in it.
(a little late, I know...)
The old TI-30 came with a book: "The Great International Math on Keys Book", which had real-world applications for a basic scientific calculator, including a lot of neat woodcut-style drawings and diagrams, plus calculator games. The later TI-36 came with a more mature version called "Student Calculator Math Book".
Never it's too late for sharing a good suggestion. Thanks.
