But all of those are available in a 50$ android phone as well. Arguably not as usable, but around 100$ the difference to an iPhone at 7x the price is not that much.
Not to mention, a 2 year old iPhone will probably sell for $250-350, while a $100 smartphone will probably sell for $25 after 2 years. This makes the difference more like $300. So, "Do you get ~$0.50/day more out of an iPhone than you do out of a $100 smartphone?" becomes the new question.
You spend $600 on food and necessities. Because you need to survive.
To me it seems interesting that a lot of people here want to play up the excellence of iPhones.
Isn't it a bit strange to make the assumption that somebody who owns an iPhone can't afford to own an iPhone?
What I'm suggesting is that perhaps we'd be served better to not assume somebody "can't afford" something, and spend a bit more time learning why they decided they can afford that thing.
