The Pew Research Center has released a study on the mobile device usage in the US.
Here’s their summary:
Nearly two-thirds (63%) of cell phone owners now use their phone to go online, according to a new survey by the Pew Research Center?s Internet & American Life Project. We call them ?cell internet users? and define them as anyone who uses their cell phone to access the internet or use email. Because 91% of all Americans now own a cell phone, this means that 57% of all American adults are cell internet users. The proportion of cell owners who use their phone to go online has doubled since 2009.
