Conducting a research on "Benefits of open source software to African
Universities", and I'm conducting a survey, with respect to the research.

I need points to add to the survey, to that would be valid to the research.
I already have a few obvious point which are;

Number of computers in the institution,
Computers that run on open source OS and those that dont.
What are the daily application of these systems by the school
administration.

Any other ideas and tips on how this research should go would be
appreciated.
