Overall the introduction of electronic textbooks has been highly successful. The ability to carry around a mobile library on a pocket sized device is a fairly impressive technological achievement. In addition, the ability to have a well referenced handbook accessible and available at any time is very attractive. It will be interesting to see how this section of the textbook market grows as the number of smart devices increases. For this market to remain successful, publishers and developers alike are going to have to work hard to adapt their texts and marketing strategies to current economic conditions.
