http://www.thinksecret.com/news/0501expo5.html Road to Expo: PowerBook speed bumps to 1.5/1.67GHz confirmed By Ryan Katz, Senior Editor January 10, 2005 - Armchair Apple watchers can add another item to the itinerary of Apple CEO Steve Jobs' Macworld Expo keynote tomorrow: PowerBook G4 updates. Mobile warriors will be disappointed to hear that they'll have to wait a little longer for the already long-awaited PowerBook G5--expect an announcement, possibly, at WWDC in June, sources say--but the speed bump will breathe some life into a line that has gone without an update since April of last year. At the high-end, the new PowerBooks will top out at 1.67GHz, sources say. Other chances will be similarly minor: the 80GB/4200RPM hard drive found on the current high-end 15-inch and 17-inch models will be replaced with 100GB hard drive spinning at 5400-rpm. The video card at the high-end will remain ATI's Radeon 9700, but it will be given a boost from 64MB of memory to 128MB. The PowerBook SuperDrive will also gain official support for DVD+R media, along with the DVD-R discs that have always worked. At the low-end, the 12-inch PowerBook will be upgraded to 1.5GHz. Hard drive size will remain at 60GB, but the drive will be upgraded from a 4200-rpm model to 5400-rpm drive, marginally improving performance. Other specifications will remain unchanged from the current 12-inch PowerBook. All PowerBooks will also be upgraded to the new Bluetooth 2.0 specification with Enhanced Data Rate, introduced in November. Bluetooth 2.0 is about three-times faster than Bluetooth 1.1, consumes less power, and is backwards compatible with Bluetooth 1.1 devices.
