PowerBook G4

The first 12" PowerBook G4 was introduced in January 2003 at US$1,799 with a Combo drive (a SuperDrive was available at extra cost). It has an 867 MHz CPU, requires Mac OS X 10.2.4 or later, and includes 256 MB of RAM (128 MB on the logic board, and expandable to 640 MB according to Apple - or 1.125 GB based on field reports) and a 40 GB hard drive.
The 12" PowerBook was cousin to the 12" iBook, which it shared many features with. It was the first PowerBook in ages not to include a PC Card slot, and the 1024 x 768 display was identical to that in the iBook. And unlike the iBook, the PowerBook allows monitor spanning
The aluminum-clad 12" PowerBook was slightly smaller and lighter than the 12" iBook.
Featured introduced with the 12" iBook G4 include built-in Bluetooth, AirPort Extreme support, and Nvidia GeForce 4 4200 graphics. Unlike larger aluminum PowerBooks, the 12" model doesn't support gigabit ethernet or have a FireWire 800 port.
PowerBook G4/1 GHz
Eight months later Apple upped the ante with a 1 GHz version of the 12" PowerBook. It looked the same, but it now included 256 MB of RAM on the system board and officially supported a maximum of 1.25 GB of RAM.
This model also added DVI support (with a mini-DVI to DVI adapter), which the earlier version didn't include, and used the Nvidia GeForce FX Go5200 graphics processor with 32 MB of RAM.
Also new is USB 2.0.
PowerBook G4/1.33 GHz
The 12" PowerBook took a big leap forward with the introduction of a 1.33 GHz model in April 2004. In addition to one-third more CPU power, video RAM was bumped from 32 MB to 64 MB, the system bus was boosted from 100 MHz to 133 MHz, and ATA/100 drive support was added.
PowerBook G4/1.5 GHz
The final revision of the 12" PowerBook was unveiled in January 2005. With a 1.5 GHz CPU, it was about 15% faster than its predecessor, and the SuperDrive model included an 8x SuperDrive.
Apple upgraded to Bluetooth 2.0 with this model. AirPort Extreme became a standard feature with this model, which also includes a scrolling trackpad and a sudden motion sensor.
The 12" PowerBook was replaced by the larger, more powerful 15" MacBook Pro in January 2006 and the 13" MacBook in May 2006.
