Findings of The ECAR Study of Undergraduate Students and Information Technology, 2008, from the EDUCAUSE Center for Applied Research investigates use and ownership of laptops, internet-ready mobile phones, etc., and what they do with them. "It analyzes the responses of 27,317 freshmen, seniors, and community college students at 98 colleges and universities in the United States to a web-based survey, as well as findings from a focus-group."
As a librarian, one of the most interesting tables was Table 1 in the "Key Findings" (p.4) of this report which shows "Student Computer and Internet Activities." At the very top of the list is Use the college/university library website with 93.4% of the students engaged, and a weekly median frequency of use. The Associated Demographic Factor was 4-year institutions/social sciences, so I can't celebrate too hard, but it still warmed the cockles of my heart.
I've only skimmed this, but it's pretty interesting to see what students are up to with the technology.
