The latest TiBook introduced in April 2002 came with some important upgrades. Most notably was the 800MHz processor added to the top of the line model, and the 133MHz bus and L3 cache added to all both models. The PowerBook G4 now runs quite a bit cooler thanks to the use of two fans and changes made to the architecture of the processor. (The previous models ran hot enough to warm up your coffee.) Also, AirPort reception has been impproved, as has screen brightness.
