Yeah, all that's different is: * new processor architecture (counting GHz isn't too useful any more, and it bursts to 3GHz+ anyway) * faster memory (1600 v

Yeah, all that's different is: * new processor architecture (counting GHz isn't too useful any more, and it bursts to 3GHz+ anyway) * faster memory (1600 vs 1333) (DDR3 vs DDR3L (whatever that is)) (edit: DDR3L sounds like lower-power-usage DDR3) * newer graphics cards (intel 4000, "iris( pro)?", beefier nvidia) Not saying they shouldn't have done more - I'm simply avoiding that debate entirely. But you're not comparing Apples to Apples, and even if you were they're still upgraded.
