Improvements and Innovations of the Next Generation 15 Inch Macbook Pro

Unibody

The MacBook Pro boasts Apple’s new Mac computer design concept: the unibody. The unibody is a laptop casing manufactured with incredible precision from a block of aluminium. The result is not only a laptop that looks fantastic with its brushed finish and smooth edges; it’s also more than capable of absorbing the rough and tumble of life on the move.

Furthermore, the unibody has enabled Apple to make the MacBook Pro lighter and thinner. This powerful, feature-packed laptop now weighs just 2.49 kg (5.5 pounds), and at its thickest point is 2.41 cm (0.95 inch).

The monitor

The MacBook Pro’s 15.4 inch monitor is still an LED backlit glossy widescreen with 1,440 x 900 pixel resolution. The fact that these specs haven’t changed is certainly no cause for concern because the quality is first-rate. Apple has managed to enhance it, however, with a glass front that stretches across the whole of the interior surface and does away with a metal frame. The glass looks better, is tougher and lasts longer. It’s also free from arsenic, a toxin released when glass is recycled.

Multi-Touch trackpad

Another striking feature of the MacBook Pro is the larger, more versatile trackpad. The smooth etched glass of the trackpad now has a surface area 39% greater than before. This gives you plenty of room for your fingers to make every trackpad signal.

These signals have also developed, and now incorporate some useful extras. Apple has introduced a four finger swipe, for example, that takes full advantage of the trackpad’s size increase. Swipe four fingers to the right or left, and you trigger Application Switcher. This allows you to view all your open applications. Swipe four fingers up or down, and you prompt Exposé to show desktop or all your open windows.

If you’re more used to right-hand clicking, the trackpad gives you the chance to do this by tapping with two fingers. It’s also possible to arrange for the trackpad to give you a specific right-hand click zone.

Current Mac owners will spot the lack of a button lying along the bottom of the trackpad. Apple has replaced this by simply turning the whole trackpad into a button. In other words, you can click the trackpad anywhere on its surface.

Mini DisplayPort

The new Mini DisplayPort connector on the MacBook Pro is a tenth of the size of a normal DVI port. It provides a fast, no-nonsense method of connecting the 24 inch Apple Cinema Display, or peripherals such as projection systems. Various Mini DisplayPort adaptors also enable you to connect VGA, DVI, and dual-link DVI monitors.

Cinema Display

Apple’s 24 inch LED backlit Cinema Display is the perfect complement to the new MacBook Pro. It’s just what you need if you’re making a presentation, or you just want the advantages conferred by a larger screen. Apple has also designed the Cinema Display so that you can connect and use the MacBook Pro as simply as possible. Similarly, you can disconnect with ease and walk away with the MacBook Pro at short notice.

The Cinema Display’s cable, for instance, branches into three connectors. One of these goes into the new MacBook Pro’s Mini DisplayPort; another plugs into a USB port; and the third is a MagSafe that you connect to the MacBook Pro’s Power Port. In other words, you can display your images on both the MacBook Pro and the Cinema Display; use the Cinema Display’s iSight camera, microphone, and speakers; and charge the MacBook Pro via an adaptor built into the Cinema Display.

NVIDIA graphics

Apple has teamed up with NVIDIA to produce an integrated graphics processor that’s ideal for professional applications and advanced games. The NVIDIA GeForce 9600M GT graphics processor comes with dual-link DVI support and, for the 2.4GHz 15 inch MacBook Pro, has 256MB of GDDR3 memory. The memory capacity doubles to 512MB on the 2.53GHz and 2.8GHz MacBook Pro models.

This isn’t the only graphics processor in the new MacBook Pro, however. Recognising that users will sometimes require less intensive power, Apple also installs the NVIDIA GeForce 9400M processor with 256MB of DDR3 SDRAM shared with the main memory. This means you can save battery power by opting for the 9400M whenever you’re working on your day-to-day applications.

Storage

Storage on the new MacBook Pro has increased to 250GB on the 2.4GHz model, and 320GB on the 2.53GHz. Both of these hard drives run at 5,400 rpm, but you can opt to increase the speed to 7,200 rpm if you choose. There’s also a 128GB solid-state drive available.

The environment

Apple’s innovations continue with the MacBook Pro’s environmental credentials. Traditionally, laptop manufacturers have used brominated flame retardants (BFRs) in logic boards; PVC in cables; arsenic in glass components; and mercury in the CCFL (cold cathode fluorescent lamp) backlights of LCD monitors. Apple has successfully eliminated these toxins from the new MacBook Pro.

Apple has also worked hard to ensure every aspect of the design and manufacturing process considers environmental impact. As a result, the new MacBook Pro reaches the gold standard of EPEAT (electronic product environmental assessment tool). EPEAT measures the way in which a product affects the environment; the amount of energy it consumes; and the ability to recycle its parts. A gold rating is proof of Apple’s ecological commitment.

The new MacBook Pro also meets the exacting standards required to give it Energy Star status. In fact, the MacBook Pro uses just 33% of the electricity needed for one light bulb.

A high calibre product

The new 15 inch MacBook Pro has a range of exceptional features as well as industry-leading improvements in technology and green standards. With the unibody, it also has a remarkable design concept. Put all these innovations together, and you have a truly superior laptop.
