I've been an Apple user since 2006 when I bought my MacBook CD. I love it. But I want to upgrade to Lion and need a C2D. While I'd love to buy a brand new one, I'd rather save my money and get an older one. With all the different models, I really don't know what to look for, or which ones to stay away from. I just upgraded to a 750GB HDD and I have 2GB of RAM, although I'm not sure I'll be able to swap the RAM into the new one. I would probably like to have at least 4GB. Also, a black MacBook would be nice, but not necessary. If this is in the wrong place, please feel free to move it.
