The Pew Internet & American Life Project today released a report entitled  A Typology of Information and Communication Technology Users, part of its excellent series of free research reports.

According to the press release:

These findings come from the Pew Internet Project’s typology of information and communication technology (ICT) users. The typology categorizes Americans based on the amount of ICTs they possess, how they use them, and their attitudes about the role of ICTs are in their lives. Ten separate groups emerge in the typology.

This report is not focused on gadgets but on usage and so would be quite useful for any web publisher or marketer trying to reach people via Web and mobile communications.
