A Fox News article points to a research study done by the Pew Internet and American Life Project that found that nearly 50 Percent of Americans have little use for Internet and cell Phones.
In a nutshell the findings are:


8% are avid and voracious users of all things high tech
23% of users embrace technologies for social networking and employment
10% rely on mobile devices
10% use tech devices but find them a bother
49% use tech devices occasionally or are hostile towards high tech

The groups are broken down into 10 different groups of users with one group (8%) being referred to as the "Lackluster Veterans".
