The Joybook S57 is a higher-end, 15.6" notebook computer from BenQ. Powered by a 2.53GHz Intel Core 2 Duo dual-core processor, the S57 is most notable for its optional Blu-Ray drive. The CPU, up to 4 GB of RAM, and discrete ATI Mobility Radeon HD 4650 graphics should enable strong performance in most games and other demanding applications. The S57 is not highly portable, though, with a weight of 5.3 lbs and thickness of 1.4" at its rear. In addition to four standard USB ports, it features an HDMI port for viewing HD content on external displays. The notebook also features a 2.0MP webcam with noise-cancelling microphone for VoIP applications, and a 4-in-1 card reader. Battery life is estimated at 2.5 hours in power-saving mode.
