Hey guys. I have a White colored Macbook and as I don’t like the white color at all, I would really love to replace my Macbook to get a Black Macbook. but before I do that, tell me is there any difference between the two? I have heard that White colored Macbooks are quite battery efficient. Is that a joke of some kind? Can I get the white macbook replaced with the black macbook through the help of some online store? If not, then tell me how can I do this with the help of some cover shop and how much would they charge from me. Thanks.
