At the moment i have 2 mbas at home and the displays are different. my first mba had some build issues..so i called apple and they just sent me a second mba. the second mba's display lighting is much brighter especially at the edge of the screen. so the colours are worse and the black is not black any more...so i'm not sure what to do: i want the screen of my first mba and the build quality of the second one
