Yes, you are missing something big: the majority (by far) of development work is done on Windows or some Linux platform these days and has been for a long while. In fact, outside the Bay Area I could count on the fingers of one hand the number of developers I ever saw using a Mac. The valley and certain developer "scenes" have a huge overrepresentation of Mac users.
