Hi Guys, I bought a MacBook Pro in Late 2008, and I've decided to buy the new Retina Display Pro. It would be fantastic if I could get a ballpark figure of what to expect for my MacBook Pro on Craigslist or Ebay. I have a: MacBook Pro (15-inch, Late 2011) with Applecare warranty until Dec. 2014 In perfect functioning and cosmetic condition, includes the box and charger. Battery holds a full charge. I got all the upgrades, the HD screen, 16GB ram... just under $3,000 at the time of purchase. - Upgraded 2.4 GHz i7 Processor - Upgraded 16GB of high-speed 1333MHz DDR3 memory - 750GB 7200-rpm hard drive - Upgraded hi-res 15.4-inch (diagonal) LED-backlit glossy widescreen display with support for millions of colors at 1680x1050. - ATI Radeon HD 6770M graphics processor with 1GB of GDDR5 memory - FaceTime HD camera - Thunderbolt port - Full-size backlit keyboard with 78 (U.S.) or 79 (ISO) keys, including 12 function keys and 4 arrow keys (inverted T arrangement) - Multi-Touch trackpad for precise cursor control; supports inertial scrolling, pinch, rotate, swipe, three-finger swipe, four-finger swipe, tap, double-tap, and drag capabilities - OS X Lion I'd really appreciate any input or what you think it might be worth now. Thanks!
