In Digital Immigrants and Media Integration: The Smartphone Is the Synthesizer, Sally J. McMillan draws insights from the lived experience of digital immigrants who are Baby Boomers and who grew up without digital mobile technologies and have transitioned to become smartphone users. McMillan traces key points in media evolution that shaped the communication tools that digital immigrants use today, demonstrating that continued incremental change has led to a shift in focus from media types to media interfaces, with smartphones becoming ubiquitous and indispensable – the smartphone, she posits, is now firmly tied to identity. Although the telegraph was the first medium to allow the message to arrive before the messenger and initiated the transition from "cool" to "hot" media, it is the smartphone that has fully synthesized communication forms and functions into a single digital and mobile device. Through collecting and analyzing these personal and public histories, McMillan finds that digital immigrants continue to seek a balance between value and ease, and between breadth and depth of communication. Scholars of communication, media ecology, and technology will find this book of particular interest.
