Hey Guys, I bought my MBP around a year ago (beginning of April), and after nearly a year of usage, it seems to have grown really strange black markings along the front edge of the laptop. It's way ingrained into the aluminum which means it has to be a sign of corrosion, something I find to be extremely unusual, given the build quality of this beaute (this is my first mac). I'm not entirely outraged (it's not a shattered screen), but it does get annoying and it is a sign of cosmetic damage that definitely isn't a part of the normal 'wear and tear'. Would my machine be eligible for a replacement? Mine's the base 2.4/2/250gb model, and I was wondering what they would replace it with. Thanks!
