A $1000 dollar computer might not be a status symbol in the western world, but a $1000 phone in your pocket, for many consumers, is. Apple's marketing and use by social media influencers has turned their brand into a status symbol. Apple isn't the most valuable brand because there tech is better, but because they have marketed themselves as a lifestyle company that makes life easier and more elegant than the competition.
Well, seeing that you can get a new iPhone for less than $500....
Besides, Apple has 50% of the phone market in the US and it’s even larger once you move up the income scale. Statistically, anyone who is an “influencer” would have an iPhone.
