Well, I dont think there's need for a personal attack here. Even though they might not be 87% faster, they are still quite significantly faster for an ultrabook and they do deliver the battery life. So I guess the OP's question can be taken as, could intel or amd or OEMs achieve the performance to power ration soon ?
Can there be a software side compensation for this lack of standardisation? Because I too don't see any hardware standard coming very soon to ARM and I don't think it can even.
But, maybe there can be a build automation which can handle all the hassle and minimize the randomness?
