Apple has added another machine to its line of Retina high-resolution display products, announcing the 13-inch MacBook Pro with Retina.
At an event Tuesday morning, the Cupertino, Calif., tech company unveiled the new Retina laptop.
The machine is just three-quarters of an inch thick and weighs 3.75 pounds. It features a 13.3-inch screen with 2,560 by 1,600 pixels. That's more than 4 million pixels, more than many high-definition televisions.
