We use Debian in teaching and office work. We study the proper Debian, and Grass GIS, Quantum Gis, Open Office and other Open Source software. The number of workstations with Debian Squeeze is ten.
I (Vasyl Cherlinka, sysadmin) chose Debian because I love Debian, and for me there is simply no other alternative. Thank you for your work in the creation and promotion of Debian.
