According the the Chronicle of Higher Education:

Colorado Community Colleges Online, a consortium of 13 institutions in the Colorado Community College System, has teamed up with Pearson Education to offer digital textbooks at a one-time cost of $49 per student. The deal is the first of its kind between a major publisher and a public college system according to Rhonda M. Epper, co-executive director of learning technology for the Colorado online system. The $49 fee is rolled in with tuition.

The article goes on to say that the digital textbook will be phased in course-by-course, with 17 courses offering the eBook option by the end of the '09 term.  By 2011, the consortium expects most students will be using the digital option.  In addition to viewing the eText online, students will also be permitted to print all sections of the eBook or purchase a black and white custom version from the bookstore.  Giving students the option to purchase a modified print version seems reasonable since students taking courses that are either reading intensive or "problem-based," like math for example, may find using an eBook more challenging.
