One look and it's clear: With over 4 million pixels on the 13" model, the Retina display on MacBook Pro is an incredible engineering feat. Whether you're retouching professional photography or editing a home movie in HD, all those pixels give your images a level of clarity you've never seen on any notebook - or any computer, for that matter. With colors so rich, vibrant and details so sharp, it's a display worthy of the world's most advanced notebook.
