15" Macbook Pro Retina - $1599

I bought a 15" Macbook Pro Retina in September because I really needed a good laptop for the start of school (I am a software engineer). Now Apple has come out with a newer version that supports 4k displays so I would like to update.

The specs are:

2.4 GHz Quad-Core Intel Core i7 Processor with Turbo Boost up to 3.4GHz
8 GB 1600MHz DDR3L Memory
256 GB Flash Storage
15.4-inch Retina Display; 2880x1800 Resolution; NVIDIA GeForce GT 650M Graphics

List price was $2200, but I paid $2000 because I am a student. Now I am selling for $1599. Has been used for 2 months. Comes in the original packaging.

Also selling a like-new 42" 1080p flat panel display for $299. Will deliver on campus for free.
