Product Specifications

Among the VAIO Z series' best in class capabilities is a revolutionary 13.1" LCD display. Scratch-proofed and anti-glare, it delivers 100% true-to-life color fidelity and extra wide 1600 x 900 resolution for deeper contrast and truly natural realization. With its carbon fiber casing the VAIO Z series notebook could hardly be easier to carry. The VAIO Z series' button, AC adapter terminal and battery are all cleanly aligned along its elegant cylindrical spine. This distinctive construction allows the jointed thickness of the screen and main body to be kept to an absolute minimum, accounting for its pristine portability. The isolation keyboard is carved seamlessly from a single sheet of aluminum, so the palm rest and keyboard form a continuous surface styled into a smooth curve at the front of the notebook. As well as looking stylish, this unique feature enhances both durability and comfort.
