Announced in January 2003, The PowerBook G4 (12.1") brough the subnotebook form factor of the 12" iBook to the G4 line. Housed inside an Aluminum case even smaller than the iBook, The 12.1" G4 had nearly all the features of the 867 MHz PowerBook G4 Titanium, and a few more to boot.

The 12.1" G4 was based on a new motherboard design, which included Double Data Rate RAM, internal BlueTooth, and AirPort Extreme (54 Mbps 802.11g) support. The 12" PowerBook G4 included a 32 MB NVIDIA GeForce4 420 Go graphics card, and borrowed the iBook's mini-VGA port. It came in a single configuration, with 256 MB of RAM and a 40 GB hard drive, for $1799. A SuperDrive configuration, with a 60 GB drive was also available for $1999.
