"If you publicly express an opinion that any particular platform is best for a significant portion of buyers, you’re effectively saying that the people who chose differently were _wrong_."<p>That's the fallacy right there. "A is better than B" does not imply "B is bad".<p>But a fanboy, who's gotten his identity and sense of self-worth tangled up with his product choices, has made a tremendous effort to rationalize his purchase of A to the point where he believes B must be bad. Any evidence that B is not bad forces him to rationalize the evidence away.<p>Two things make it easy to slip into fanboyism about phones. The manufacturers' marketing keeps telling us that owning A will make you one of the cool kids, encouraging us to derive self-worth from the product. We also have to rationalize spending money, perhaps more money than we can afford.<p>Most of us don't get nearly so emotional about, say, shampoo, because we can easily afford to buy any brand we like or switch brands on a whim.
