I recently purchased a new 15" macbook pro. I'd like to sell my now-older macbook. Is there a Kelly-blue-book for mac's (laptops) any where on the web? If yes, I haven't found it. Can anyone help me put a value on my 13" macbook. I believe I paid $1100 new and it has never had a problem. I have the original box, install cd and apps cd, and booklets. It is three years old, running 10.5. 2gig ram, 2gig processor and a 160gig hard-drive and has a 13" screen. The Apple Store just did a new OS on it for me. Thanks for any help?
