I disagree, though based on the attitude of your comment I'm not sure if you'll take my point.
Here in Dublin, at least, iPhones are becoming extremely popular, even with the losertechnicians of the world. Businessmen with no tech skills are replacing Blackberries with them, teenagers are flocking to get them, and there are even dodgy-looking iPhone accessory shops in bad neighbourhoods.
Over here, since around the start of this summer, the iPhone 4 has been available for free on a 40 euro per month contract with unlimited data and enough minutes/texts for the vast majority of people, on pretty much every network. That's a really good deal, and a huge number of people bought into it, figuring that they spend at least that on credit anyway.
When the iPad 2 launched over here, there was a period of 8 months where you could not find ANY, at all, even in the authorized resellers that Apple likes the most. At any one time there might have been one for sale in the whole city.
Android is gaining momentum here too, and I don't know figures for any of this, but I definitely haven't seem them on as many non-hackers as I have iPhones.
In conclusion, no, the people who have iPhones are not the Apple-savvy hipsters. At least in this city.
