The excerpt blog DT>Digital Textbooks pointed me at the following infographic. It's quite simple and it actually contains only one data point. It's something I knew but had never put together before: the rental cost of a digital textbook vs media subscriptions.
Students can get a Spotify and Netflix subscription for about the same cost as a single Coursesmart digital textbook. One the one hand, ~$20 gets them access to tens of thousands of songs, movies, and TV shows, while on the other hand they get a single textbook.
Gee I wonder which is the better value?
I know that this is an overly simplistic example but it is still mostly true.
