The PowerBook G4 was the name of a series of Mac OS X-based notebook computers manufactured, marketed, and sold by Apple Computer, Inc. (called Apple, Inc. today) between 2001 and 2006 as part of its PowerBook high-powered "professional (pro)" line of notebooks. As the name suggests, these PowerBooks ran on the RISC-based PowerPC G4 processor, designed by the AIM (Apple Inc./IBM/Motorola) development alliance and initially produced by Motorola. It was built later by Freescale, after Motorola spun off its semiconductor business under that name in 2004. The PowerBook G4 had two different designs: one enclosed in a titanium body with a translucent black keyboard and a 15-inch screen; and another in an aluminum body with an aluminum-colored keyboard, in 12-inch, 15-inch, and 17-inch sizes. When Apple switched to Intel x86 processors in 2006 the PowerBook G4's form and aluminium chassis were ported to the new Intel-based MacBook Pro, albeit with several minor alterations (such as a different port layout, the addition of a built-in iSight camera, and the elimination of the 12" model).
Between 2001 and 2003, Apple produced the titanium PowerBook G4; between 2003 and 2006, the aluminum models were produced. Both models were hailed for their modern design, long battery life, and processing power. When the aluminum PowerBook G4s were first released in January 2003, however, only 12-inch and 17-inch models were available. The 15-inch retained the titanium body until September 2003, when a new aluminum 15-inch PowerBook was released. In addition to the change from titanium to aluminum, the new 15-inch model featured a FireWire 800 port, which had been included with the 17-inch model since its debut nine months earlier.
