TAb Pro S is AMOLED screen and has a 2160x1440 resolution with the best blacks in town vs 2304 × 1440 on rMB, both have excellent sRGB's just different aspect ratio, the Samsung also has a touch screen and gorilla glass and is brighter.
Given that it's specs are more in line with the 2015 rMB than the 2016, but offers an excellent alternative (if not stuck on clam shell format) when you consider it negates most reasons to have a separate tablet to accompany a rMB, which IMO gives you more to gain than you compromise with these fan less M processor designs
I was thinking of picking one up so went to try it at Best Buy, but that keyboard is TERRIBLE and the trackpad is tiny so it was a really poor laptop experience compared to pretty much any premium ultrabook or even the SP4 type cover.
