This doesn't really explain why some of the brands with the most ardent fanboys are those that don't have a big presence marketing directly to consumers: say, Boeing vs. Airbus, or AMD vs. Intel. For the great majority who aren't particularly familiar with those industries, which brand someone identifies with doesn't tell us anything - what does it mean to be an Airbus fanboy rather than Boeing? Not being an aviation geek myself, I really don't know!
