The Sony VAIO Z-series is one of the smallest laptops we've ever seen, but it still tries to cram in everything you'd expect on a full-size notebook. Its 1.47kg weight is far less than most notebooks, and it's light enough to barely be noticeable when slung in a bag. The 33mm thickness is another reason why the Z-series is ideal for frequent travellers, as long as you've got a well-padded bag for added protection. An ultraportable without compromise: plenty of power, great battery life and superb design.

NVIDIA GeForce 9300M GS: Compared to the 9300M G, the GS has only 8 unified shaders but a higher clock rate. Therefore, the performance should be similar according to Nvidia. Supports
Hybrid-SLI (GeForceBoost and HybridPower) with Nvidia 9100M G and PureVideo HD (VP3).
Only some 3D games with very low demands are playable with these cards.
Intel Core 2 Duo: This is the Core Duo and Core Solo successor with a longer pipeline and 5-20% more speed without more power consumption. As an addition to the Core Duo design there exists a fourth decoder, an amplified SSE-unit and an additional arithmetical logical unit (ALU).
The Core 2 Duo for laptops is identical to the desktop Core 2 Duo processors but the notebook-processors work with lower voltages (0.95 to 1188 Volt) and a lower Frontside bus clock (1066 vs 667 MHz). The performance of equally clocked notebooks is 20-25% lower than Desktop PCs because of the lower Frontside bus clock and the slower hard disks.
The P9600 is a middle class dual-core CPU of the Core 2 Duo line and similar to the T9550 (except for the lower TDP of 25 vs 35W). The performance of the P9600 should be sufficient for most applications and games of 2009.
