 15" Titanium PowerBook G4 The Apple PowerBook G4 is a notebook computer manufactured by Apple Computer, and initially powered by PowerPC G4 processors produced by Motorola, but now produced by IBM.
The first generation of PowerBook G4s were announced at Steve Jobs' keynote at MacWorld Expo in January 2001. It featured a titanium enclosure and a Motorola G4 running at 400 and 500 MHz. It was just 1 inch thick, 0.7 inch thinner than its predecessor, the PowerBook G3. The PowerBook G4 Titanium was nicknamed "TiBook". Optical discs (initially DVDs or CDs) were inserted into front-mounted slot-loading optical drive.
The PowerBook Titanium product line was updated several times, with features such as Gigabit Ethernet, DVI connectors and an optional SuperDrive DVD burner. The last revision was released in November 2002, in 867 and 1000 MHz models.
The current generation, released in April 2004, consists of three models: 12", 15", and 17" widescreen in an aluminium enclosure. Notably, Yao Ming and Verne Troyer did commercials for the 12" and 17" models. The 17" model is also one of the few laptops in production with such a large display. Their specifications range from 1.5 GHz to 1.67 GHz; 512 MB to 2 GB of RAM; 60 to 100 GB of hard disk space; the nVidia GeForce FX Go5200 and the ATI Technologies Radeon 9700 Mobility GPUs and many other features.
The Titanium PowerBook G4s are capable of running Mac OS 9 or Mac OS X operating systems, while the Aluminum PowerBook G4s are incapable of running Mac OS 9 from startup. Both series of machines can run Mac OS 9 in Classic Mode from within Mac OS X.
