Consider this; not all "Universities and Schools" teach primarily Computer Science. There are plenty of students that don't want to use an operating system that is completely foreign to them and very removed from what they use at home. I recall when the G5 Powermacs came out, I was angry because the biggest lab, the one for our literature science and art students (versus Engineers) had gotten first dibs at the powermacs. This stuck me as ludicrous because the students were using these fantastic video editing work horses to write e-mail, write reports, and browse the web between classes. Another point I would like to make is that Universities often get technology donations by companies like Apple and and Dell. At my school, the Dells on the engineering network dual boot to redhat. (strangely enough, there are some sun boxes that run windows as well) Billions of taxpayer money? Do you have a real number for that? And do you have some cost improvement number for a education wide transition to Linux inclusive of the cost of sysadmins (and the cost of only being able to afford novice students as sysadmins)? Do you even care about the end-user experience (in this case, students)? Somewhere in your head, perhaps sitting under the gluttonous weight of empty zealotry, must be the notion that switching completely to Linux at a University with varied programs is completely infeasible. How does that switch affect business students, film and video students, music students? Computers are utilities that have become very useful for nearly everyone in some way. Linux is not useful in those same ways. It would just be idiotic for a business student to go into a job interview and not be able to claim being proficient at Microsoft Office.
