With the new laptop lineup being more confusing as ever, I was wondering what the performance gap between the new MacBook Air and the MacBook Pro nTB from 2017 really is. 1) What is the difference between the Y and U-series CPU's in the two machines, and how will it affect e.g. FCPX editing? 2) What is the difference in graphics performance between the two? 3) Is there a difference in the screen's color range (color gamut) and brightness between the two?
