MacBook Pro 15-inch 2.4GHz  full review
Upon the first look at the new MacBook Pro 2.4GHz, you could be forgiven for thinking little has changed. It still shares the same size and aluminium colour of its predecessor, but that's where all similarities end.
Both inside and out, the new MacBook Pro 2.4GHz has been completely remodelled, redesigne and reengineered. Make no mistake: this is a completely different laptop to the one it replaces.
While all the previous Macbook Pros felt rock solid, the new models seem even more so due to the brand new manufacturing process introduced with this generation of MacBooks and MacBook Pros. Instead of assembling the laptops piecemeal and expertly splicing the components together, the new models sport a unibody architecture that constructs the entire machine out of a single piece of recyclable aluminum. Such assembly, according to Apple, eliminates the need for fine-tuning parts and diminishes the possibility of construction failures. With the new MacBook Pro in hand, it feels almost like an extension of your arm. There’s no clasp keeping the lid shut: simply grip the thumbscoop etched into the bottom of the case, and it opens right up. Even without a clasp, it feels secure when closed.
The unibody composition also makes these new laptops easier to service and fix, and great for do-it-yourself types who have, in the past, lamented how difficult it was to do things like swap out the hard drive or battery. The new MacBook Pro makes it very easy to access the battery and hard drive—move the lever on the bottom of the case, and you’re in. Upgrading RAM requires the removal of eight screws; the previous MacBook Pro had only three screws.
