I must say I am a bit disappointed with this product. Sure, it outperforms most every ultrabook on the market (though if the "ultraportable" class, with full voltage mobile cpus were not made obsolete, it would fall to the middle of the pack), but not by nearly as much as I had hoped. For the price, I am not sure I see the benefit of a 50% price premium for perhaps 20% better performance when it doesn't lift the capability to tasks its lower price competitors cannot equal. Until both the OS and applications can make good use of resolutions over 1080p the extra cost of higher resolution displays strikes me as nothing but marketing gimmics that we have to pay for. I would be happy with the successor to the Asus UX31A with Haswell cpu/gpu, the same screen and concomitant improvement in battery life and performance, for around $1,300-$1,500 vs. over $2,000. Excellent review.
