Case Scenario:
Robbie Trencheny, an 18-year-old high school senior, loaded half a dozen textbooks and novels into his Nook digital reading device as soon as he received it as a birth-day present from his parents this month.
"I don't have to carry textbooks with me anymore," said Trencheny, who also bought a few books on the device for leisure reading. "Plus, e-books are cheaper than most normal books." But Trencheny was one of the lucky ones. Barnes & Noble Inc.'s Nook reader,which can hold 1,500 digital books, was sold out weeks ago, and anyone ordering it now is not expected to receive it until February.
Note: If prices is below equilibrium, the quantity demanded exceeds the quality supplied. The willingness to pay the advertised (list) price of $259 didn't ensure purchase of a Nook e-reader in 2009.
