eBooks slow to catch on with technologically hip

An Associated Press article on e-books and the slowness with which they are catching on quotes Lewis Mandell, professor of finance and managerial economics, who writes and publishes his own e-textbook and says that because "The investment world is changing on a weekly basis. Tax rates change every year," he's able to update his finance books more frequently. The article appeared in more than 40 outlets, including USA Today.
