PowerBook G4 upgrade
Sonnet Technologies today introduced its new for PowerBook G4 550MHz and 667MHz (VGA) models. The upgrade features a Freescale 7457 G4 processor running at 1.2GHz, and offers 512K of L2 on-board cache--twice that of the original processor. Sonnet says it has opted to start the new full-service upgrade because of the complexity of replacing the PowerBook CPUs. The service includes the purchase of the upgrade, full installation, and testing of the upgraded computer by trained technicians. Sonnet sends out a custom padded shipping box for the notebook allowing customers to pack the device and ship it back to Sonnet, after which the company ships the device back to users fully upgraded and ready for use. The PowerBook upgrade service costs $500 and is compatible with Mac OS 9.2 as well as Mac OS X through version 10.4.x.
