You (and some others in the thread) seem to think that marketing is some kind of trickery or magic which carries no value to the buyer. You're also trying to commodify a phone.
But you don't buy two ounces of phone. You don't buy one and a half tonnes of car.
When you buy a product, you're paying for the product, the marketing, the wraparounds, the integrated and soft services. That's the case for an Apple iPhone. It is also the case for Starbucks, Costa, Nero coffee. Coffee and beans is a few pence. You're mostly paying for the marketing - the lifestyle brand buy-in.
It is also the case for Sony Vaio, Levi Jeans, GAP clothes and A&F tshirts. It's the case for everything.
What matters to you might not matter to someone else. You might buy by the GHz. I might buy by the gram.
If you want to reduce every single thing in this world into its core components and materials, then according to you, everything is overpriced. But that'd be fallacious and not representative of reality..
Well, I remember seeing an interview once with Beyonce and her mum advertising their fashion range, and all the clothes that the models and Beyonce were wearing were just $18. So yes £5000 jeans are hugely overpriced.
