context_page_description: The PowerBook is a family of Macintosh laptop computers designed, manufactured and sold by Apple Computer, Inc. from 1991 to 2006. During its lifetime, the PowerBook went through several major revisions and redesigns, often being the first to incorporate features that would later become standard in competing laptops. The PowerBook line was targeted at the professional market, and received numerous awards, especially in the second half of its life, such as the 2001 Industrial Design Excellence Awards "Gold" status, and Engadget's 2005 "Laptop of the Year". In 1999, the line was supplemented by the home and education-focused iBook family.
  The PowerBook was replaced by the MacBook Pro in 2006 as part of the Mac transition to Intel processors.
context_section_description: Interim CEO Steve Jobs turned his eye to the redesign of the PowerBook series in 2000. The result, introduced in January 2001, was a completely re-designed New World PowerBook with a titanium skin and a 15.2-inch wide-aspect screen suitable for watching widescreen movies. Built with the PowerPC G4 processor, it was billed as "the first supercomputer you can actually take with you on an airplane." It was lighter than most PC based laptops, and due to the low power consumption of the PowerPC it outlasted them by hours.
  The TiBooks, as they were nicknamed, became a fashion item. They were especially popular in the entertainment business, where they adorned many desks in Hollywood motion pictures. Because of their large screens and high performance, Titanium Powerbooks were the first laptops to be widely deployed as desktop replacement computers.
  The industrial design of the notebooks quickly became a standard that others in the industry would follow, creating a new wave of wide-screened notebook computers.
  The Titanium PowerBooks were released in configurations of 400 MHz, 500 MHz, 550 MHz, 667 MHz, 800 MHz, 867 MHz, and 1 GHz. They are the last PowerBooks able to boot Mac OS 9.
  In 2003, Apple launched both the largest-screen laptop in the world and Apple's smallest full-featured notebook computer. Both machines were made of anodized aluminum (coining the new nickname AlBook), featured DVD-burning capabilities, AirPort Extreme networking, Bluetooth, and 12.1-inch or 17-inch LCD displays. The 17-inch model included a fiber optic-illuminated keyboard, which eventually became standard on all 15-inch and 17-inch PowerBooks. Two ambient light sensors, located under each speaker grille, adjusted the brightness of the backlit keyboard and the display according to the light level.
  The 12-inch PowerBook's screen did not use the same panel as that used on the 12-inch iBook, while the 17-inch PowerBook used the same screen as that used on the 17-inch flat-panel iMac, but with a thinner backlight.
  Later in 2003, the 15-inch PowerBooks were redesigned and featured the same aluminum body style as their smaller and larger siblings, and with the same feature set as the 17-inch model (including the backlit keyboard). This basic design would carry through the transition to the Intel-based MacBook Pro, lasting until late 2008.
  In April 2004, the aluminum PowerBooks were upgraded. The SuperDrive was upgraded to 4× burning speed for DVDs, the fastest processor available was upgraded to 1.5 GHz, and the graphics cards were replaced with newer models, offering up to 128 MB of video memory. A third built-in speaker was added to the 12-inch model for improved midrange sound. In addition, AirPort Extreme cards became standard for all PowerBooks instead of being offered as an add-on option.
  In January 2005, the specifications of the aluminum PowerBooks were revised once more to accompany a price decrease. Processor speeds were increased to a maximum of 1.67 GHz on the higher specification 15-inch and all 17-inch versions, while the lower specification 15-inch model and the 12-inch unit saw an increase in speed to 1.5 GHz. Optical audio output was added to the 17-inch version. Memory and hard drive defaults were increased to 512 MB and 5400 rpm, respectively, with a new storage maximum of 100 GB on the 17-inch model. Each model also received an enhanced trackpad with scrolling capabilities, a revised Bluetooth module supporting BT 2.0+EDR, and a new feature that parks the drive heads when sudden motion is detected by an internal sensor. Support for the 30-inch Apple Cinema display was also introduced in the new 17-inch model and was optional in the 15-inch model via a build-to-order upgrade to the computer's video hardware. The SuperDrive now included DVD+R capability.
  In October 2005, the two higher-end PowerBooks were upgraded once again, with higher-resolution displays (1440 × 960 pixels on the 15-inch model, and 1680 × 1050 pixels on the 17-inch model) and faster 533 MHz DDR2 (PC2-4200) memory. The SuperDrive became standard equipment and included
