The 15.4" MacBook Pro Notebook Computer from Apple 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! Scratch and Dent products are systems with considerable cosmetic blemishes that do not affect performance. They are a great way to save money while still enjoying a rebuilt and rigorously tested device. Scratch and Dent computers will not have scratches or pits on the screen, missing or illegible letters on the keyboard, or damage to the touchpad or palmrest.
