A revamp of Apple's PowerBook line of laptop computers will see the company earn more from portables than desktops this year. Speaking at the annual Apple Expo in Paris last week, Apple chief executive Steve Jobs unveiled a new 15-inch PowerBook, along with upgrades for its 12-inch and 17-inch notebooks and a new wireless keyboard and mouse. During his keynote address, Mr Jobs enjoyed the usual cheers from the 5,000-strong crowd when he unveiled the new series of laptop computers. He said 42 per cent of Apple computers sold during the last quarter were portables models, versus an industry average of 24 or 25 per cent. He said he hoped sales of portable computers would soon equal its sales of desktop computers. 'I think we can see that happen in the not too distant future,' Mr Jobs said. 'This is clearly the year of the notebook for Apple.' The new 15-inch PowerBook runs on a 1.25 gigahertz PowerPC G4 processor with 512KB of level 2 cache, an ATI Mobility Radeon 9600 graphics card with 64MB RAM, up to 2GB of memory and a 60GB or 80GB Ultra ATA/100 hard drive. It also has high-speed Airport Xtreme and Bluetooth wireless networking and built-in Gigabit Ethernet (10/100/1000BASE-T), USB 2.0 and FireWire 800 ports. The case and keyboard have been remodelled to match the 12-inch and 17-inch PowerBooks, both of which have been given faster processors, more memory and better graphics cards. However, Apple fans hoping to scoop up the first generation of titanium PowerBooks at clearance prices will be disappointed. William Chan, marketing manager for Apple Hong Kong said stores had already sold their stock and had held off placing new orders until the new units were announced. 'We've sold out of all the old models,' he said. 'A lot of people have been expecting new PowerBooks to be released soon.' The new 15-inch sells for HK$15,900 for the 1GHz model and HK$20,900 for the 1.25GHz model with superdrive. The upgraded 12-inch PowerBook is HK$12,900 or HK$14,500 (both 1GHz), while the new 17-inch unit with a 1.33GHz chip is HK$23,900, Mr Chan added that while local channels had already sold out of older PowerBooks, some older iMacs were still available. However, he did not reveal figures. Apple also launched a wireless mouse and keyboard - products that the company was criticised for not releasing with its revamped iMac range last year. The Bluetooth devices can connect to a computer from up to 30 feet away and protect their signals with 128-bit encryption. They also feature frequency hopping software to avoid those used by other wireless devices.
