Hi, I'm looking at getting Applecare for my 15" MBP bought in Feb last year. I've found a seller on ebay who has them boxed and sealed for a good price. The thing is, he has some with product number MA515ZM/A and some with product number MA259ZM/A. As far as I can tell the difference is that the 515 one is for powerbooks as well. Does that mean it's an out of date product or will it still cover my MBP? I can't find the 515 product anywhere on the apple website. Thanks in advance.
