The new design was a sharp departure from the black plastic, curvilinear PowerBook G3 models that preceded it, more modernist than ergonomic. The initial design of the PowerBook G4s was developed by Apple hardware designers Jory Bell, Nick Merz and Danny Delulis. 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. The PowerBook G4 Titanium also featured a front-mounted slot-loading optical drive into which optical discs (initially DVDs or CDs) could be inserted. They were just 1 inch (25 mm) thick, 0.7 inches (18 mm) thinner than their predecessor, the PowerBook G3. They featured a PowerPC G4 processor running at either 400 or 500 MHz.

When the Aluminum PowerBook G4s were first released in January 2003, however, only 12 and 17 inch models were available. Both models were hailed for their modern design, long battery life and processing power.
