Acer has thrown down the gauntlet in its race-car rivalry with Asustek Computer, launching the latest upgrades to its Scuderia Ferrari series of notebook PCs, the first dual-core additions to the family.The Ferrari 5000 laptop and smaller Ferrari 1000 are based on Turion 64 X2 mobile processors from Advanced Micro Devices, and are designed to compete with Asustek\u2019s Lamborghini laptop, which is based on a dual-core Pentium M by Intel.The main difference between the new Acer laptops is size. The Ferrari 5000 comes with a 15.4-inch screen, while the ultra-mobile Ferrari 1000 sports a 12.1-inch screen.The 5000 is housed in a thin and light carbon-fiber casing and comes in black and Ferrari red, the same colors as all of Acer\u2019s Ferrari laptops. It includes a voice-over-IP handset that connects to the laptop wirelessly via Bluetooth, as well as a 1.3-megapixel Web camera mounted just above the liquid crystal display screen.\n\n\n\n\n\n\n\n\n\nAcer Ferrari 5000 It\u2019s also wireless LAN-ready for 802.11a\/b\/g, and has a high-capacity, 160GB hard drive, as well as a choice for users between a DVD super multi-double layer drive or an HD-DVD drive.The Ferrari 1000, which also comes with a webcam, is designed for mobility, weighing in at 1.7 kilograms\u00a0(3.7 pounds). Both laptops come with Microsoft Windows XP Home Edition or Microsoft Windows Professional x64 Edition installed, as well as Adobe Reader, Norton AntiVirus, and CyberLink PowerDVD and Power Producer.Details about pricing and availability are expected at the Computex trade show in Taiwan next week. The Ferrari 4000, an earlier model with a single-core Turion processor, sells in the United Kingdom\u00a0for between 799 pounds and 1,279 pounds (US$1,490 and $2,390), depending on the model, according to Acer\u2019s website.\n\n\n\n\n\n\n\n\n\nAcer Ferrari 5000 -Dan Nystedt, IDG News ServiceFor related news coverage, read Greenpeace Plans Protests at Computex.Check out our CIO News Alerts and Tech Informer pages for more updated news coverage.
