I think some with the money to burn would rather have the storage and not use it that not have it and need it, especially since Apple doesn't have external storage slots.I think some people ignore the obvious. You can tell people who buy the large-capacity iPhones that they don't need all that storage, but they're going to want it anyway. Why? They simply want what they perceive to be the "best" or "top of the line." Everyone knows this is true with other products, especially products in the luxury category. Few people may need 512 GB of storage on their phone, but the lure of simply owning it is quite powerful.
