I found the exact MBP I have been looking for on craigslist. I'm set to meet the guy tomorrow. The story, the price and the guy all seem legit. We will be meeting in a public place and I'll bring a (big and intimidating) friend. But neither of us have used macs and I don't know what might be broken or what to look for beyond cosmetic dents/scratches. It was purchased in August and I know the yellowing screen is an issue to be concerned about. I've read the thread about the issue and have the pictures to test with, but I haven't found video or pics of a bad screen. I will get the original receipt with the laptop. If the bottom of the screen is yellow, is it covered by Apple? Anything else to look for? How do I check the processor to make sure it's the 2.4? Thanks in advance. I'm excited to join the mac community and no longer just be jealous.
