Apple flat out ignores their legal obligations with warranty, so I don't see that as a factor. I had the logic board replaced in my year-and-a-bit-old MacBook and got a massive bill ($1400+), laughed and told them that the warranty was two years in Australia, and it was miraculously replaced with a $0 fee with no questions asked. If I'd not known and paid it, they'd have ripped me off for the value of the machine.
