I am a professor of mathematics at NYU with interests in atmospheric and climate science.
I use Ubuntu for my home desktop and laptop and swapped from Fedora because of apt-get and the attention paid by Ubuntu devs to out of the box performance.
At work I run a personal linux cluster with 24 opteron cpus and RHEL3.
