Fanboy Theory

Most rational people will not get mad if someone loves a particular product. But they will get mad if someone is constantly insulting the product choices that they have made.
It's fine to love one product and not like another. But don't let condescension, even if it is subtle, come out while you are discussing it. That is what brings the blow back.
That's the fallacy right there. "A is better than B" does not imply "B is bad".
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.
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.
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.
2. What companies you choose can be seen as a single pieve of what some perceive as an ideological struggle. Google the defender of openness, and Apple the harsh dictator, managing user experience with an iron fist.
3. People have their phones nearby nearly 24/7. It's possible a subconscious attachment to it develops in people, though I don't know the psychology of it.
