My screen cracked a few months ago, but it has just been getting worse recently so I've been looking into replacing it but I have a few questions. First, I should be looking at "Apple MacBook Black Mb062Ll/B Laptop LCD Screen 13.3" WXGA," correct? And secondly, is there anything stopping me from replacing it with a matte screen instead of glossy? The difference in price is only like $3 and I would definitely prefer matte. Thanks for any help.
