PowerBook G4 (15” Double-Layer SD)

Introduced: October 2005
Terminated: February 2006


The PowerBook (Double-Layer SD) did not improve on the processor speeds of the previous models, instead it bumped up the RAM and the screen resolution and, most notably, offered a dual layer SuperDrive.  There were two configurations available, the 15.2” model and the 17.1” model.


The last release under the very long-lived PowerBook name, the PowerBook G4 (Double-Layer SD) was unusual in that it did not increase the processor speeds.  This was probably due in most part to the fact that G4 processor would have been too hot at higher speeds.
