The Apple 15.4" MacBook Pro is a powerful notebook computer with an innovative aluminum unibody design. It is loaded with advanced power management features and an integrated battery, which work together to provide up to 7 hours of wireless web browsing. You may notice an unfamiliar logo next to one of the ports on the left side of the system. This is Thunderbolt, a high-speed interface that can move data at an amazing 10Gbps, which is double that of USB 3.0. The Thunderbolt port also doubles as a display output because it shares the same physical form factor as a Mini DisplayPort. You can daisy-chain up to six devices, so you'll be able to connect high-speed external storage and an external Apple LED Cinema display via the same port! The computer's 15.4" display features LED backlight technology and a glossy finish. Its 1400 x 900 native resolution gives you ample screen space to work with. You'll be able to output to an external display at up to 2560 x 1600 via Thunderbolt. Any Mini DisplayPort-compatible display will plug in without the need of an adapter. If you have a display with DVI, VGA or HDMI input, you'll only need to purchase an adapter cable (i.e., HDMI-to-Mini DisplayPort) for connection.
