I am a senior studying Marketing and Information Systems at the University of Idaho. I have all three of my machines (one horrible, one not so bad, and one OK) running SETI@home, but I don't think my roommates know it (they're borrowing the first two computers).
Thoughts about SETI and SETI@home
I do believe extraterrestrial life exists, but I don't think we'll discover it in any way other than remote sensing (SETI@home, chemical analysis, etc.).
