I don&#x27;t think this is actually true.<p>The second iPhone model (iPhone 3G) was actually thicker than the original. When iPad mini went retina, it got 1mm thicker. iPhone 6S is slighter thicker and heavier than iPhone 6, which I find noticeable.<p>Also, maybe cost in the US hasn&#x27;t changed (but that&#x27;s disingenuous because iPhone was originally almost completely subsidised by your carrier), but in Australia, the base cost for latest gen iPhone used to be $799. Now, the iPhone 6S 16GB is $1079.<p>Of course, lots of things have happened for Apple to raise their prices in Australia - consumer protection laws changed (well, Apple started following them differently) significantly increasing the cost of providing a warranty. Also I&#x27;m sure the exchange rate has caused prices to change (though I&#x27;m not sure in which way - I think it&#x27;s gotten worst though).
