The PowerBook G4 series was Apple's workhorse portable for five years, with slim metal cases and fixed internal components (no more battery/drive bays!). The more advanced Aluminum models replaced the Titanium cases and added Airport Extreme and Bluetooth capabilities.
While PowerBook G4 models vary dramatically in construction, all can be easily upgraded. With the exception of the Aluminum 12" (with one slot), all PowerBook G4 machines have two RAM slots for an easy memory upgrade. Want to burn CDs or DVDs? Drop a Superdrive in your machine to do it all!
