Not sure why you decided razer stealth @1.4K is closest to what Mac has to offer when they have a "regular" razer blade in the same price range as the mbp with the only upside to mbp being a better battery life (which is most likely due to a superior but hungrier video setup on the blade).

speaking of battery life - not sure that once you get into 6 hrs vs 8hrs type difference it's all that important.
