In 2003 Apple introduced a new line of PowerBook G4s with 12- 15 and 17-inch screens and aluminium cases (prompting the new moniker "AlBook"). The new notebooks not only brought a different design to the PowerBook G4 line but also laid down the foundation for Apple’s notebook design for the next five years, replaced initially in January 2008 by the MacBook Air and the subsequent MacBook and MacBook Pro redesigns in October. The 15" Titanium was still available until September 16 2003 when the Aluminium model replaced it.

Notably, the 12" model brought a welcome return to the Apple subnotebook configuration, conspicuously lacking in their product line since the discontinuation of the PowerBook 2400 in 1998. While the Titanium PowerBook G4s were capable of running Mac OS 9 or Mac OS X operating systems, the Aluminium PowerBook G4s could only boot in Mac OS X from startup. Both series of machines could run Mac OS 9 in Classic mode from within Mac OS X.

The first generations of the PowerBook G4 were announced at Steve Jobs' keynote at MacWorld Expo in January 2001. They featured a PowerPC G4 processor running at either 400 or 500 MHz. They were just 1 inch (25 mm) thick, 0.7 inches (18 mm) thinner than their predecessor, the PowerBook G3.

The PowerBook G4 Titanium also featured a front-mounted slot-loading optical drive into which optical discs (initially DVDs or CDs) could be inserted. The notebook was given the nickname "TiBook", a portmanteau of titanium, the material used for the computer's case, and the brand name PowerBook, Apple's professional-oriented line of laptop computers.

What is Power Book G4?

The PowerBook G4 is a series of notebook computers that was manufactured, marketed, and sold by Apple Computer, Inc. between 2001 and 2006 as part of its PowerBook line. It uses the PowerPC G4 processor, initially produced by Motorola and 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" screen; and another in an aluminium body with an aluminium-colored keyboard, in 12", 15" and 17" sizes.

Between 2001 and 2003, Apple produced the Titanium PowerBook G4; between 2003 and 2006, the Aluminium models were produced. Both models were hailed for their modern design, long battery life and processing power. When the Aluminium PowerBook G4s were first released in January 2003, however, only 12 and 17 inch models were available. The 15 inch retained the titanium body until September 2003 when a new aluminium 15 inch PowerBook was released. In addition to the change from titanium to aluminium, 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.

The PowerBook G4 line was the last generation of the PowerBook series, and was succeeded by the Intel-powered MacBook Pro line in the first half of 2006.
