So I was looking up prices of unlocked iPhone 6 and iPad Air 2 cellular models, and noticed that for some reason, given the same size, the iPhone is more expensive than the iPad. In the US store, the iPhone 6 64GB model costs $749 while the iPad Air 2 64GB cellular costs $729. While the difference here is $20, in other markets (my home market of Korea for example), given the same storage size, the iPhone costs just under $900 while the iPad Air 2 costs $800; the difference is much more pronounced. I was going to attribute this to miniaturization costing more, but if that logic were to stand, the iPhone 6+ should be cheaper than the iPhone 6, but as most people know, it isn't. Is it just marketing that makes the iPhone more expensive?
