A few years back, I had a 6-year-old white uni-body MacBook with a swollen battery that was long out of warranty. I made an appointment at the Apple Store, and when I took it in, they took one look at the battery, gave me new battery and sent me on my way. They didn't even mention the word warranty. I was there for 5 minutes. I had zero expectations going in, so was quite happy and impressed with their response.
