I bought the 15" rMBP on release day and the past couple of months i've began noticing small white "clouds" in the bottom left and right hand side of my display. I assume it's a Sharp display. Anyway how do I have Apple replace it? I didn't buy apple care or anything... Do I just go to an apple store (closest one is 2 hours) and see what they say or can I call and ship my laptop. Thanks beforehand!
