Apple PowerBook G4 Titanium

Released by Apple in 2001, the PowerBook G4 Titanium was notable for its robust, lightweight titanium enclosure. It was also groundbreaking for its inclusion of a massive 15-inch widescreen display, which was a rarity for laptops at the time.

It was powered by the Motorola PowerPC 7440 G4 processor, initially running at speeds of 400 MHz or 500 MHz. This processor was specifically optimized for multimedia tasks and graphic design, heavily utilizing Apple's AltiVec 'Velocity Engine'.

Internally at Apple, the PowerBook G4 Titanium was developed under the codename 'TiBook'. It eventually paved the way for the aluminum unibody Mac laptops that Apple introduced later in the decade.

Despite its premium materials, the TiBook was infamous for its brittle hinges, which were prone to snapping after heavy use. Additionally, the painted titanium surface often suffered from flaking and bubbling due to the user's palm sweat.
