The amazing retina display
I agree with you. I bought the 15" version of the retina screen. A friend let me view a photo of the Biltmore Mansion in North Carolina he took a couple of weeks ago with a Nikon D4 (16MP). I was blown away by the clarity of the tree limbs and the people on the lawn and the details of the building. On top of all that, the display is a high quality IPS (In Plane Switching) screen, which aren't used in laptops usually.
