This is interesting, particularly as a test for e-ink; however, it is worth noting that the VitalSource Library has been delivered on over ~400,000 computers in K-12. The Library includes over 2500 classics from literature, history, and the arts, as well as a dictionary (Oxford or Houghton-Mifflin) and, depending on the version, thesaurus or encyclopedia (Britannica).
Most private schools with laptop programs include the product in their image and LAUSD (the second largest school system) images it all instructional machines (Gateway, Dell, Lenovo, HP, and Apple). As I believe you (David) know, VitalSource’s BookShelf software takes full advantage of the digital environment with an XML-based format that is reflowable and searchable (across entire libraries of content and notes). Learners can also highlight, takes notes and share notes with other BookShelf users.
