If you want fanboys make sure your product confers social status. Concentrate on aesthetics and make sure you're almost always more expensive than the competition. Good aesthetics make your product desirable, an expensive price point means your product will keep its social status.
Yeah I don't think its necessarily easy. Other people have to know that the product you're buying is 'impressive' for it confer some status. Its also about building a brand identity that people want to associate themselves with. So Apple spends a lot of money making sure people know they are the cool Californian company.
Apple does marketing right, like all the good premium brands. But that doesn't lead to fanboyism. In what other arena do you see people taking sides and insulting each other about stuff that pretty much does the same thing, no matter which they choose? American politics.
The fanboy thing happens cuz personal computing is a dual party system. You're either a Mac or a PC. Or you're one of those weird 3rd party candidates who use Linux.
