Apple switched to the Inter Core 2 DUO 64-bit processor, then also added many features like a dual-layer DVD burner and FireWire 800, a larger 120 GB hard drive, 1 GB of RAM, and a now unlocked 802.11n AirPort Extreme. Apple was also able to improve the cooling, which allowed them to speed up a grossly underclocked ATI Mobility X1600 and be more competitive. The result were 2 brand new laptops: Apple MacBook Pro with 15″ and Apple MacBook Pro with 17″.
The aluminum build feels solid and looks good. A backlit keyboard and auto-dimming LCD backlight make this laptop easier to use in low light while the colors do not seem washed out or over exaggerated.

When it comes to sound, the speakers are weak, not ever comparable with the ones on dell or toshiba, so you might thing about getting external ones for a lauder and clearer music. I consider this notebook suitable for games because the new Core 2 Duo version processor combined with the fact that the ATI Mobility Radeon X1600 was able to run the X1600 at a higher clock speed since the improved cooling, will conclude in perfect high speed quality visualization. As for noise, the original Core Duo MacBook Pros were silent, and while not as quiet, the same holds true for the new Core 2 Duo upgrade.

The keyboard still uses ambient light to brighten and dim in the same fashion as the LCD screen, and the touchpad has a generous amount of space (maybe too much in case you accidentally click on it) and a single button, but what really makes it stand out is the two-finger scrolling feature. Input and Output Ports include 2 USB 2.0 ports and single FireWire 800, a FireWire 400, gigabit Ethernet, mini optical audio out, microphone in, and a ExpressCard/34 slot. As for wireless features, it possesses the AirPort Extreme WiFi card and Bluetooth 2.0. Battery life is improved up to 5 hours.
