The Titanium PowerBook G4 (nicknamed TiBook) When Apple switched to Intel x86 processors in 2006, the PowerBook G4's form and aluminum chassis were retained for the MacBook Pro. The first generation of the PowerBook G4 was announced at Steve Jobs' MacWorld Expo keynote on January 9, 2001. The two models featured a PowerPC G4 processor running at either 400 or 500 MHz, housed in a titanium-clad case that was 1 inch (25 mm) deep. This was 0.7 inches (18 mm) shallower than the G4's predecessor, the PowerBook G3. The G4 was among the first laptops to use a screen with a widescreen aspect ratio. It also featured a front-mounted slot-loading optical drive. The notebook was given the unofficial nickname "TiBook", after the titanium case and the PowerBook brand name it was sold alongside the cheaper iBook. The 1 GHz version of the Titanium G4 is the last, and fastest, PowerBook that can natively run Mac OS 9 (version 9.2.2). The initial design of the PowerBook G4 was developed by Apple hardware designers Jory Bell, Nick Merz, and Danny Delulis. The ODM Quanta also helped in the design. The new machine was a sharp departure from the black plastic, curvilinear PowerBook G3 models that preceded it. The orientation of the Apple logo on the computer's lid was switched so that it would "read" correctly to onlookers when the computer was in use. PowerBook G3 and prior models presented it right-side-up from the perspective of the computer's owner when the lid was closed. ![]()
