WHEN SONY KICKED OFF ITS SZ SERIES OF ULfRAPORTABLES WITH THE VAIO VGN-SZ170P, the company showed that it was the first to understand how important discrete graphics and an optical drive were to performance-seeking world travelers. Battery life was the only element that stood in the way of an SZ-series.The SZ791N is the latest refresh. It keeps intact the successful compact design while providing a compelling performance boost with one ofIntel's new Penryn processors, a 2.5-GHz Core 2 Duo T9300. The SZ791N sustained over 5 hours of battery life, enough to earn it an Editor's Choice in the ultraportable category.
The 13-inch LED screen is amazingly thin-not to mention bright-but the way the lid flexes raises some concerns about possible damage to the LCD. The SZ791N continues to be one of the few ultraportables that run discrete graphics. The n Vidia GeForce 8400M GS chip set lets you run many current 3D gaming titles. MobileMark 2007 tests tallied 3 hours 49 minutes of battery life with its 63-Wh battery. Intel's latest CPU helped the SZ791N deliver a blend of performance and battery life. For that, it earns our coveted Editors' Choice.
