Abstract
The 2009 competition was the fifth year of the Schubmehl-Prein contest for the Best Essay on Social Impact of Computing. The competition is open to high school juniors each year, with a submission deadline at the end of May. The essay topic varies each year, with the 2009 topic being, "What are the potential social and ethical implications of the $100 laptop?" The 2009 competition attracted a number of essays that strongly engaged with the topic. The 2009 First Place winner is Katherine Heit, the Second Place winner is Danielle Harris, and the Third Place winner is David Purington. In addition, this year, for the first time, two Honorable Mention winners were also selected: Bryan Dongre and Erica Smith. Revised versions of the First, Second and Third Place essays appear in this issue of Computers and Society. Congratulations to all of this year's winners. Thanks to all of the students who prepared and submitted an entry to the competition. And thanks as well to all of the teachers and school counselors who worked with all of the students.
