Many theaters are already sold out for the premiere of the latest film in the Harry Potter series, "The Half-Blood Prince."

Fans will pay around $9 apiece for 2 hours and 20 minutes of spooky entertainment. For J.K. Rowling fans, however, this is some of the most expensive Potter-time on the market; each minute will cost the viewer $.064.

Expensive compared to what, you ask? Compared to those take-anywhere, electricity-independent, high-value things called books. Books are a 39% better value.

How so? The average reader reads 250-350 words per minute. Let's use 300 for our example.
