I've just got a 15" retina macbook pro. And the color of the screen seems to vary in different places, particularly the bottom left corner has a yellow/green tint. Its not enough to quantify or easily point out, but enough to be annoying. Have others noticed issues with the display? like some people had yellow patches on the iphone 4s(?) If I take it too the Apple shop will they be able to do anything, as I'm not too sure they would be able to notice it (it's more obvious when using it for long periods of time).
Also the Apple site says you should be able to get 7 hours of battery life, but currently I'm on 100%, nothing running except Safari and everything off except Wifi (screen darkness at minimum) and the menu bar item says 5 hours until the battery runs out. Will it be 7 hours in reality? Or is this unusual?
