RE: What's the point of digital textbooks?

The digital textbooks are being offered at substantially lower (about 33%) prices than the paper versions. And they expire sometime after the end of term.

There is only one point, and that is to kill the aftermarket of used textbook stores.

Publishers want to collect revenues every time a book changes hands, but recent court decisions have prevented them from doing so. They think they have a chance of doing this with self-destructing digital media.

It's not unlike subscription-based software - you want the customers to keep paying and paying and paying for the same product in order to fatten your revenue streams.
