Ben points to a Newsweek article about Technology on Campus. From his post:

The average [US college] student:

* uses a cell phone
* has a laptop or desktop computer
* listens to an iPod or other mp3 player
* has an entry in facebook
* will check syllabus and hand in assignments through the web

In addition, a report from Pew Internet (PDF) tells us:

Some 57% of online teens create content for the internet. That amounts to half of all teens ages 12-17, or about 12 million youth. These Content Creators report having done one or more of the following activities: create a blog; create or work on a personal webpage; create or work on a webpage for school, a friend, or an organization; share original content such as artwork, photos, stories, or videos online; or remix content found online into a new creation.
