Carved from a single block of aluminum, the MacBook Pro is a true engineering achievement. Its patented unibody enclosure is the product of precise machining. The new energy-efficient architecture in the MacBook Pro, gives you dramatically longer battery life. On a single charge, the battery in the new 13-inch MacBook Pro lasts up to 10 hours, and youíll get up to 1000 full charge and discharge cycles ó thatís nearly three times the lifespan of typical notebook batteries. MacBook Pro gives you more options for high-performance graphics, starting with the new NVIDIA GeForce 320M integrated graphics processor in the 13-inch model. Itís up to 80 percent faster than the previous generation and is even more energy-efficient for everyday tasks like writing email and surfing the web. Every MacBook Pro has a pristine LED-backlit display with wide-angle viewing and a color gamut usually seen only on a desktop display. So whether youíre watching a movie or making one, youíve got the perfect canvas. The ultrathin, seamless glass enclosure makes the display strong and durable. And because itís power efficient and free of mercury and arsenic, this display is greener than ever. The 13-Inch MacBook Pro has advanced Intel Core 2 Duo processors. It also comes standard with a large hard drive offering up to 250 or 320GB of storage capacity, so thereís plenty of room for your photo libraries, video projects, and files. And of course all MacBook Pros come standard with Mac OS X v10.6 Snow Leopard Operating System and iLife.
