The latest information on cell phone usage vs smartphones, great article, lots of good information!
Pew Research Center's Internet and American Life Project did a survey on how American's interact with their cellphones in their day-to-day life. Pew says that nearly 83% of the U.S. population owns cellphones, 35% of which are smartphones (as of May 2011) and that the most popular ways to use the device are for text messaging and taking pictures.
The study shows how cellphone usage (especially smartphones) is changing the dynamic of how people interact with the world around them. Think back five or 10 years - how has the way you interact with media, knowledge and people changed because of the cellphone in your pocket?
