I just bought a brand new Nvidia Macbook White from Amazon. Love it so far. One problem,and I will post a pic,there is a small nick on the top left corner of the casing of the screen. Its noticeable but otherwise the computer is great,no keyboard flex that I can see or any other cosmetic issues. Would it be worth it to go through the whole Amazon exchange for just this issue with no guarantee that the replacement would be any better?
