...although there's relatively little cost justification for the jump from the dual-core i5 to the dual-core i7; the lowest end quad core in the MBP 15" is still much faster for most workloads than the dual-core i7 and the speedbump from the middle-of-the-lineup i5 to the i7 dualcore in the MBP 13" is marginal.
That said, I'd certainly agree that the MBP 13" is pretty much the sweet spot in the Apple lineup (and has been, for general use, for years -- hardly just the current retina version, although it's a very nice machine.)
It's really use dependent I suspect. I have both and don't notice any performance difference. The screen on the MBP I notice. And the MBP is current generation while the Air is older.
