I've been reading a lot of threads about scratches and coating peeling off from macbook pros. However, I wasn't able to find yet something concrete about it. I have a 2009 macbook pro 15", a macbook air 11" 2011 and now a macbook pro 13" 2015. I never had issues with the first two, despite packing them the same way, and despite using them exactly the same way. However, the later, has some scratches on the screen caused by the keyboard. Apple said that they will replace the screen free of charge as it is still under warranty, but I wonder how common this issue really is, and what can I do to prevent it. I don't feel like having to carry a microfibre cloth all the time. I'm always careful to not put too much pressure on the mac when carrying it on a backpack, and I clean the screen with the microfibre cloth apple gives with the computer so I wonder how to prevent this or if it was just bad luck. I know that a couple of posts mentioning scratches doesn't necessarily mean that there is a generalised problem.
