Following speculation based around the recent unavailability of previous models, Apple has launched two new versions of its Titanium PowerBook G4 laptops. The company has also released three new iBook consumer laptops. The PowerBooks use the same feted one-inch thick titanium metal body and 15.2-inch widescreen display as the original line-up, adding faster processors and a faster system bus. There’s also a new graphics card, a CD-RW drive option and support for 1000Base-T (Gigabit) Ethernet. The first model has a 550MHz PowerPC G4 processor with 256kB of on-chip level 2 cache, 128MB of RAM and a 20GB hard drive – while the second has a 667MHz chip, the same cache, 256MB of RAM, a 30GB hard drive and a new 133MHz system bus. The 550MHz model uses the same 100MHz bus as previous Titanium PowerBooks. Both models include ATI’s Mobility Radeon graphics system with AGP4X and 16MB of video memory. RAM is expandable to 1GB, while an optional 48GB hard drive is available on purchase. Apple has also bowed to user demand and offered a CD-RW drive as part of the system as an optional replacement for the DVD-ROM drive. This choice has to be made when purchasing the system as the drives are fixed into the titanium shell. The 667MHz model also ships with a pre-installed AirPort card, Apple’s wireless connectivity system. The PowerBooks ship with Mac OS X 10.1, as well as Classic Mac OS 9.2.1. The models have a suggested retail price of $2,199 (550MHz) and $2,999 (665MHz) in the US. UK pricing has yet to be established.
