I once had a Vaio that lost paint from the volume buttons. It happened to more people. They also said they wouldn't cover cosmetic damages. I kept bugging them saying I didn't pay the extra for a premium looking laptop to have this cheap thing happening. They fixed it in the end, for free.

I have a friend that always makes a huge scene at an apple store when something breaks (latest thing was a failure of the Ati card in a iMac from 2011), he always gets everything fixed, for free. You need to have a big mouth.
