According to a new report from the Pew Internet & American Life Project, America is quickly becoming a smartphone nation:

Nearly half (46%) of American adults are smartphone owners as of February 2012, an increase of 11 percentage points over the 35% of Americans who owned a smartphone last May. Two in five adults (41%) own a cell phone that is not a smartphone, meaning that smartphone owners are now more prevalent within the overall population than owners of more basic mobile phones.

Considering the first iPhone was released just five years ago, the rate of smartphone adoption is pretty amazing. It also shows just how important mobile broadband now is in our daily lives.
