Just what a lot of you have been waiting for. Almost. It's Still a G4. Apple on Monday released a new PowerBook line featuring a scrolling TrackPad and Sudden Motion Sensor running up to 1.67 GHz, starting at $1499. The new PowerBooks come standard with 512MB memory, integrated AirPort® 802.11g, Up to 100 GB Hard drive, Bluetooth 2.0 wireless networking and the scrolling TrackPad and the Sudden Motion Sensor. Apple's new scrolling TrackPad "works with every application and document, so users can easily scroll through long web pages or across large photographs. Simply touch the trackpad with two fingers instead of one to quickly scroll or pan within the window." Also included with the new PowerBooks is Sudden Motion Sensor technology that integrates a tri-axis accelerometer that helps protect a spinning hard drive if the notebook is accidentally dropped. Apple's backlit keyboard is now built in to all 15- and 17-inch PowerBooks and is up to 10 times brighter than in previous models. “Apple continues to lead the industry with the most innovative notebooks,” Apple’s senior vice president of Worldwide Product Marketing Philip Schiller said. “With new features like the scrolling TrackPad and Sudden Motion Sensor, the new PowerBooks are the ultimate combination of performance and portability.” Starting at $1499, the new PowerBook models will be available later this week at the Apple Store online, Apple’s retail stores and Apple Authorized Resellers.
