I don't get the same impression I have to say. I see more snobbery aimed towards Apple products by suggesting they are inferior and the people who buy them only do so for the brand, and have indeed myself been in that position a couple of times. I'm yet to find an iPhone owner who looks down on somebody else because of what phone model they use. Apple market simplicity and logic, rather than suggesting their customer base are a certain type of person in my view. I think internet discussion gave birth to what you are saying here rather than it being a reality. Again I think this is your impression rather than it being representative of what the mainstream think.
Sorry but i don't think snobbery that is aimed at apple buyers. It is more the ridicule of paying extra for the brand sticker.
Also I said on average not every apple buyer is a snob. It is well accepted that Apple users have higher brand loyalty and more passionate and willing to pay more for something that does less. Just this alone would lead to more snobbish outlook. I think the reality is more like this. You don't hear of anyone selling their kidney to buy a Samsung do you?
