But people do that with Android too? How many people upgraded from an S2 to an S3 just because it was new, and didn't actually need any of the new features?
I know a lot of folks with iPhones, they are common as muck nowadays, and none of them are up their own arse about it. They just see it as another phone.
What's that specifically got to do with "Android" though? This kind of behaviour, while not exclusive to Apple products, is definitely strongly associated with Apple products.
iPhones are common as muck, not everyone is up their own arse over it, but the ones that are make up for the ones that aren't as they simply must let everyone know how great the phone is.
It's the whole "preachy" aspect of it that people tend to get annoyed by, the regular verbatim quotes of Apple marketing slogans as reasons why their Apple product is "the best".
