A block of metal: Instead of many minor parts, the new MacBook has just one: the new, solid-aluminum unibody enclosure which makes it thinner and much lighter.

A better keyboard:The illuminated keyboard, a popular feature of MacBook Pro and MacBook Air, now comes standard on the 2.4GHz MacBook model. To add to this the trackpad doubles as a button—just press down anywhere to click. No separate button means there is more room for your fingers. The Multi-Touch gestures bring all functions to your finger tips — use two fingers to scroll up and down a page, pinch to zoom in and out, swipe with three fingers to flip through your photo libraries, rotate to adjust an image with your fingertips.

Clear view: Inside, the aluminum enclosure is perfectly integrated with a glass overlay that stretches to the edge of the notebook, providing a completely unobstructed picture. The LED-backlit display is power efficient as well as mercury and arsenic-free, making it greener.

Better gaming: The NVIDIA GeForce 9400M brings up to five times faster, discrete-level graphics performance ensuring high-end, high-speed 3D game-playing power. Graphics-intensive features in iPhoto and iMovie are smooth and responsive.

A Wi-Fi agent: With the latest 802.11n wireless technology built into MacBook, you’re always connected. It also has up to five hours of wireless productivity battery life.
