From John Horrigan of the Pew Internet Study: The decline in home broadband adoption mirrors the rise in "smartphone only" Americans, and the pattern is most noticeable for lower and lower-middle income households, minorities, and rural Americans. A plurality of non-broadband users (33%) say the monthly cost of service is the main reason they don't have service, with another 10% saying the cost of the computer is the main barrier. People more than ever say they see the importance of home high-speed service. Comparing 2010 to 2015, people are much more likely to say it is a major disadvantage not to have home broadband service -- and the change is driven mainly by non-broadband users saying this. We've heard for years now about the cost of digital exclusion -- now, non-broadband adopters especially are cognizant of it, but service is out of reach for a lot of them.
Smartphone only users do not have the same quality of access as home broadband subscribers. As Pew has documented, the smartphone dependent are more likely than other smartphone users to run up against data caps or to suspend service for financial reasons. When asked to compare modes (broadband v smartphone), people are more likely to prefer a desktop or laptop computer on their home broadband connection for watching video or doing education- or healthcare-related information activities.
