Although a little dated (2009) this is a nice summary of key issues on mobile content delivery across mobile technologies.
Also, this video highlights how corporations are concerned with mobile content delivery. Although this is not directly applicable to education, it describes the importance of effective content delivery across devices. Some of the issues also reminded me of Kenny and Park’s study on Using Mobile Learning to Enhance the Quality of Nursing Practice Education.
