E-books with teeth!

R Hadden Writes:

The Wall Street Journal has a story today about a new idea in
electronic publishing- renting e-books and textbooks. A new dental textbook
at the New York University is available on a DVD. The students pay an
annual fee to keep the books updated, and there are strict controls on
downloading the information. At graduation time, the book erases itself
unless additional subscription funds are paid to the publisher, Called
VitalBook DVD, this systems incorporates a method of storing textbooks,
class notes, video and other media on a DVD. The cost to dental students at
NYU is about $5,000.00 for all four years of school.
