While I agree with much of the discussion thus far surrounding the cheek of the US carriers charging what they do and always attempting to force consumers into a tiered plan rather than letting them keep their grandfathered unlimited data plan without any throttling

, I'm going to take a slightly different approach here, even though in the amount of time it's taken me to comprise my thoughts, others have likely touched upon the same subject...
The iPhone 5S costs somewhere around $200 to make. This is also the standard subsidized price of the base 16 GB model at most US carriers. However, to buy the device outright with no subsidy costs over 3X that much, meaning Apple is pocketing quite a bit...
Now, I've been a proponent of Apple for over a decade. My experience with their products, both hardware and software, have made my days building Windows PCs from the ground up seem like a frivolous effort due to the infinitely better user experience that I
personally found through their products. I feel like they understand the end user experience concept better than any other company out there.
That being said, a 325% markup for a product that has sold like hotcakes... really?? I get R&D costs, marketing, payroll, support, etc. But the fact that a 16 GB iPhone 5S at the full price of $649 costs $30 more than a 16 GB iPad Air with cellular at $629, while the iPad costs only around $15-60 more to build than the iPhone?... I've always believed that you get what you pay for, and again, I feel like I get a better product for my money when I buy Apple. But the Apple price point has also been the primary point of contention for many of my friends & colleagues who've waffled at the premise of switching.
However, Samsung's Galaxy S4 is also $649 at its unsubsidized price, and its build cost is only slightly higher than the iPhone 5S, so...
Shouldn't some of the frustration be directed at the makers of the devices to put a more reasonable price point on their devices?
Another bit of perspective: Sony and Microsoft are both taking a pretty substantial profit hit on their latest next-gen consoles. Granted, the smartphone market is substantially larger than the console market, but still... if smartphone makers cut their unsubsidized pricing down to even 200% of the build cost, I'd be willing to bet that many more people than just me would still buy it, and it would still be profitable. Not as profitable as it's been with the carriers choking down the extra cost, mind you, but it seems to me they'd still be in the black.
Just a thought...
