All that power, wasted because of a limited operating system designed for phones, not for tablets.
iOS isn't limited internally.
The front-end paradigm is currently single full-screen window at the moment.
It isn't inconceivable that Apple will add UI multitasking ability (i.e., split-screen operation) in a future iOS update. It's what form this comes in that is the question. A 4:3 screen could be treated as two 2:3 screens next to each other for example, you drop from @3x to @2x in the rendering, and most apps can cope with different vertical heights.
However difficulty comes if you want different sized screens, or more advanced configurations. Never mind drag-and-drop between open active applications, and similar functionalities that two applications to be open at the same time can offer. I presume that windowed operation is not going to be offered.

I am curious if the iPhone 6/6+ are getting throttled more heavily. I mean how can the single core score be that much higher off a 100Mhz clock difference? Look at the Air 1 vs iPhone 5s for reference.
Yeah, typically in mobile applications processors run in a low speed most of the time (active, not sleep), and only go up to their rated speed when absolutely required. That period of high speed can also only be maintained for a certain amount of time before it's throttled down a bit to keep power consumption/heat under control. It's called Race To Idle and doesn't work well with intensive games and long running benchmarks!
It's likely that the larger chassis of the iPad Air 2 can take a lot more heat than the iPhone 6+, so it can run at its top speed for longer, even though that top speed is higher.
