Now that I think about it, this Mini vs. Air thing is really promising for future potential multi-screen size iPhones. My biggest fear with Apple going to larger screens for the iPhone, especially phablet sized screens of 5"+, is that they'd put the best stuff in that phone, with weaker specs and such for the 4-4.5" device. The fact that the Mini and Air have the exact same internals and only differ in size makes me hopeful that if next year's iPhone release is a 4.3" iPhone 6 and a 5.3" iPhone 6+, that they'll share everything but the screen and body.
