The major physical changes on the outside is an Nvidia chipset with improved integrated graphics, while the “unibody” aluminum chassis, the button less touch pad, and edge-to-edge glass on the LED-backlit display .
New MacBook models operate on a faster front-side bus, (from 800MHz to 1066MHz) and move from DDR2 memory to DDR3.
Though the new MacBook has slower base model CPU and fire wire is missing still it represents both an impressive value and an impressive feat of engineering although it’s hard to expect anything else from Apple’s flagship computer product, which has been a consistent favorite for several years.
The white-and-black bodies have been replaced with an aluminum chassis that looks nearly identical to the new MacBook Pro, only smaller. The result is a lighter and thinner, yet stronger, frame that feels more solid and substantial a notable feat.
Another notable new feature is a radically redesigned touch pad. In fact, the entire touch pad depresses like a button, although a simple tapping (as on a PC laptop) will also work once we turn that option on in the settings menu.
Some of the new features are it can hide all apps by sweeping four fingers up on the pad, and can also designate one corner of the touch pad as a “right-click” zone. Most useful, perhaps, is sweeping four fingers left or right, which brings up the application switcher. Once we get used to it, going back to a regular touch pad would be difficult.
Apple has also added LED-backlit displays which means a thinner lid and some battery life benefits, plus the edge-to-edge glass we’re seeing more often on multimedia systems, such as the HP HDX18. The glass, however, also grabs stray light rays with ease, making the glossy screen seem that much glossier a problem if you prefer matte screen finishes.
With only two USB 2.0 ports and no more FireWire, the new MacBook isn’t exactly brimming with connections an Express Card slot and an SD-card reader the two most desire things are yet to come true, so photographers may be disappointed.
The new MacBook and its 2.4GHz Intel Core 2 Duo CPU performed comparably to its predecessor, which is to say that basic multitasking and productivity is a breeze, as is streaming and viewing HD-video content. While the hardware is largely similar, MacBooks score better on our Multitasking test than similarly configured Windows laptops (such as the Dell Studio 15), thanks in part to the efficiency of the Mac operating system.
