Apple seems to be copying Sony’s product life cycle as they introduced new 12″ PowerBooks and 17″ PowerBooks with new aluminum alloy enclosures, barely on the heels of the SuperDrive PowerBooks. Both new notebooks feature a backlit keyboard with ambient light sensors, and built-in Bluetooth, while the larger one additionally offers built-in AirPort Extreme 54 Mbps 802.11g wireless networking and new high-speed FireWire 800.
