Apple wanted this MacBook Pro to have a screen as vivid as your imagination. A screen where everything you see is remarkably vibrant, detailed, and sharp. What was created was the world's high-resolution notebook display - and their most jaw-dropping Retina display yet. When you pack over 5-million pixels into a 15.4-inch display, the results are positively stunning. The pixel density is so high, your eyes can't discern individual pixels. Images take on a... [more] high level of realism and text is pin sharp. And with a 2880-by-1800 resolution, you can see more of your high-resolution images onscreen with pixel-for-pixel accuracy. So your best ideas can become your best work. When your goal is to build the high-performance notebook of the future, you begin at its foundation. For this MacBook Pro, that foundation was flash. Because when you build a notebook around an all-flash architecture, not only is everything more durable, reliable, and battery efficient - everything is fast. Really, really fast. A long battery life is impressive for any notebook. But for a high-performance notebook with an ultra-high-resolution display, top-of-the-line processors and graphics, and a superslim design, it's absolutely remarkable. The built-in battery gives you up to 1000 full charge and discharge cycles. Which means you can put your MacBook Pro to sleep, and it'll come back on instantly - after a day, a week, or even a month. Thin and light, this notebook is designed to go anywhere - including places with less-than-stellar lighting. A built-in sensor detects changes in ambient light and adjusts the keyboard brightness automatically. So you're never left in the dark.
