Thank you for this initial post, it was very well-written and thought out. I am studying accounting and economics currently and this was a good read!
FWIW, one must consider that a user who purchases a 16gb iPhone has the option of iCloud photo library (now 50 GB @ $0.99 / mo.) - Yes for a buck a month, one has an additional 50 GB. Also, I love to keep my music library on my phone - but with Apple Music, the game is changed. I can stream it whenever. I can put hard copies on my phone for a road trip without LTE.
Would I ever purchase a 16 GB iPhone? Nope. Not a chance. 64 GB is the sweet spot for price, functionality, and revenue with current tech-amenities, and Apple knows that. Nevertheless, the 16 GB phone is totally usable, if savings of about $4 / mo. is worth it (on the new upgrade program)... You could always not buy a soda at lunch, twice a month, and you would have made up the difference in monthly cost between the 16 and 64 gig phone. What a silly world we live in to complain about such a thing.
Marketing and finance at Apple and the Carriers love you for saying this. It is so convenient right and you are saving with a smaller phone? And guess what, this logic will empty your pockets far more than the cost of more GB. Hence the whole point of this thread! The point is this won't end up being a better deal to you and the corporations know exactly what they are doing.
Apple music (9.99 per + data fees). Cloud (.99 per month + data fees). Data fees vary, caps, overages....see where this is going?
People think about cost saving now vs long term for everything. And it is a great way to take more profits.
