"MacBook Pro is machined from a single piece of aluminum, an engineering breakthrough that replaced many parts with just one. It's called the unibody. And the first time you pick up a MacBook Pro, you'll notice the difference it makes. The entire enclosure is thinner and lighter than other notebooks. It looks polished and refined. And it feels strong and durable - perfect for life inside (and outside) your briefcase or backpack."

"From editing photos to browsing the web, everything happens ultrafast. And all that power is encased in an incredibly thin 0.68-inch unibody design that weighs only 2.96 pounds. This ultra-efficient architecture was designed to use less power and still deliver high performance. Which means not only can you do whatever you want - you can keep doing it for longer than before. In addition, the Intel HD Graphics 6000 processor offers advanced performance you'll especially notice with games and other graphics-intensive tasks."
