>For one of my classes this term we did a research study. The results were interesting.
Our hypothesis was that the more technical a user is the more likely they are to use an alternate browser on whatever platform they use.
We collected a lot of data to attempt to narrow this down. The test we used was invalidated because we did not have enough technical users using IE, oops. We think it would hold true though.
Also, of note in this class FF has the majority.
