Hi everyone. I'm hoping that some of you might be able to help me out. I would like to upgrade to a macbook, but have a 12" powerbook that I need to sell first. It has 1.25 GB Ram, and 160 GB HD with Leopard. How much should I reasonably be able to ask for this laptop? It's in PERFECT cosmetic condition, all original accessories (incl. box), and brand new battery. Any advice would be greatly appreciate!! Thanks.
