Although not an Apple fan, I can relate to their purchasing behaviour through an analogy of my own:
I am a massive Pixar fan. I think almost everything they touch turns to gold and I haven't seen a Pixar movie that I dont' like (to be fair, the last new release I saw was Toy Story 3). When I saw the ad for WALL-E, I thought it sounded like a stupid idea for a movie, but I still forked out the $10 to go see it at the cinema. This decision was purely on their past record, nothing to do with my perception of WALL-E. Sure enough, I loved it.
Perhaps this is a similar way Apple fans make decisions.
