I don't see what extras Apple give me (that are worth having) over Android that are sufficient to justify the Â£500+ cost difference. They seem to do much the same thing and I can put Micro SD cards in my phone.
Of course you don't understand: you're trying to apply logic to the situation. There's a very good reason Apple iPhones are worth so much more than others: they make you feel good! Of course, that probably doesn't make sense to you because you're not thinking emotionally. You'll just have to buy an iPhone to find out. It's just like Jeeps: "It's a Jeep thing, you wouldn't understand."
I see a lot of people who claim they have no money with iPhones. I know people who claim they are broke and desperate who have iPhones, and they aren't second hand ones either.
Anyway, I know someone like this too. She's a single mom, scrimping and saving and worried about getting enough child support from her ex while struggling with a mediocre-paying school job, yet she has an expensive iPhone 6 that isn't quite even paid off yet, complete with expensive-ass full service with Verizon. The phone is barely even functional because it's so beat up that the screen frequently doesn't work, the Otterbox Defender it's in is falling apart (and looks like a counterfeit to me, as the "rubber" is falling apart plus the plastic parts are busted into multiple pieces, but this item was purchased at an actual Verizon store so supposedly it's genuine).
My current advice for phones to people who want a nice phone without spending a ton of money (and of course is what I do) is to get a used Galaxy S4 or S5 on Ebay, and to get the Sprint or maybe T-Mobile version, then sign up for service with Ting. You can get a very nice S5 now for $150-200, and an S4 for less than $100 (the S5 is a little faster, and is waterproof). The prices on these things has come down lately because of the new S7s (the non-exploding kind, it's only the Notes that explode, the regular S7s and S7 Edges don't seem to). And of course, these phones are great IMO for several other reasons: removable batteries, SDcard slots, and lots of super-cheap parts available for them on Ebay, including spare OEM batteries for less than $10. The gorgeous AMOLED screens (on both) and waterproofness on the S5 are also really nice, and they're fast enough for modern, normal usage.
In light of her phone being on its last legs and her not being in the best financial situation, I showed her my phone and told her what I was paying for service (about $20/month) and how little my phone cost, to convince her to stop wasting so much money on an iPhone and Verizon service, but she just doesn't want to give up the iPhone.
It's like an addiction IMO. There's simply no grounding in reality or practicality for having one of these things when you're on a budget, and it's really awful that people who are the least able to afford these overpriced fashion statements are the ones most convinced that they "need" them when there's so many cheaper alternatives. This isn't to say that all lower-income people are dumb enough to buy into this scam, otherwise all those dirt-cheap prepaid phones and service plans at Walmart wouldn't be selling. Sorry if this is sexist, but personally I'd love to see a study comparing people by income level, the phone they have, how much they spend on cell service, and finally, what sex they are. I'm willing to bet good money that there's more women in this trap than men.
