Adobe Digital Index’s 2014 U.S. Mobile Benchmark Report shows that the nature and use of mobile devices is changing in some unexpected ways.

At the same time, Web browsing by smaller screen phones (four inches or less) is down year-over-year. And, tablet growth is flattening, as well, in the wake of these larger phones coming to the market. Will the future of mobile browsing be ruled by “phablet” devices?
