Identity: 23 years old. First time owner of a used, scratched up, old Macbook Pro. I bought a Macbook Pro from Craigslist. It is a Late 2008 15 inch unibody model with 2.93 GHz Intel dual core processor. It had cosmetic dents and scratches on top of the machine. There was a problem with the display, a discoloration on the screen appears when it is viewed in a black background and full brightness. The machine still has Applecare until August 2012 so I got an appointment...
