College Students Are Buying More, Warez-ing Less
Keefesis writes: "This story from a researcher at the University of Florida states that software piracy among college students dropped between the 1996-97 school year and the 2000-01 school year. One reason cited is that software makers have found 'creative' ways to entice students to purchase software(rather than the heavy-handed and largely unsuccessful tactics of the RIAA)."
This is my personal answer. Using school bandwidth to get whatever flavor linux .iso and freeBSD (just to have) is far cheaper and easier than going to a store. Not to mention, most games now suck or are available for linux (rtcw).
