Apple’s line of MacBook Pro laptops was intended for the professional and power users. The MacBook Pro line includes the MacBook Pro 13″ Unibody, MacBook Pro 15″, MacBook Pro 15″ Unibody, MacBook Pro 17″, and the MacBook Pro 17″ Unibody.
The MacBook Pro laptop was first introduced in January 2006; it replaced the PowerBook G4, Apple’s earlier professional line of laptops. The original MacBook Pro model came in an aluminum enclosure, a trend that continues with this line of laptops today.
After more than two years and numerous incremental upgrades, Apple announced a completely new MacBook Pro model in October 2008, dubbed the MacBook Pro 15″ Unibody. The MacBook 15″ Unibody is a distinct update of the original MacBook Pro, packing all the previous features of the Pro into a more stylish and lighter weight aluminum enclosure.
