Future of the Internet: Pew Report

Pew / Internet has published the third installment of its The Future of Internet series where they question a group of experts on a variety of scenarios and their likelihood of coming to life by 2020. Among the highlights:  virtual and augmented reality, the future of user interfaces, and mobile.  There's even a whole book of this stuff out on Amazon.  The report makes for an interesting reading but the research methodology seems restricting (respondents have to react to pre-canned scenarios instead of suggesting their own ideas) and I'm struggling to find practical applications for the rather non-binding expert comments such as "The use of the keyboard may [?] disappear."
