The Pew Research Center's Internet & American Life Project has released Mobile Access 2010
Here's an excerpt:
Six in ten American adults are now wireless internet users, and mobile data applications have grown more popular over the last year.
As of May 2010, 59% of all adult Americans go online wirelessly. Our definition of a wireless internet user includes the following activities:
- Going online with a laptop using a wi-fi connection or mobile broadband card. Roughly half of all adults (47%) go online in this way, up from the 39% who did so at a similar point in 2009.
- Use the internet, email or instant messaging on a cell phone. Two in five adults (40%) do at least one of these using a mobile device, an increase from the 32% of adults who did so in 2009.
Taken together, 59% of American adults now go online wirelessly using either a laptop or cell phone, an increase over the 51% of Americans who did so at a similar point in 2009.
