Reviews for the Sony Vaio VGN-FZ31Z
Source: Trusted Reviews

Despite initially impressing with smart design and good features, the FZ31Z is let down by poor battery life and appalling integrated speakers. It's still a good machine in many respects, but other 15.4 inchers offer a better balance for less money, while larger notebooks can boast stronger multimedia credentials.

With the memory of HD DVD rapidly fading into obscurity, consumers can now buy into Blu-ray with new confidence. And fresh from the format's recent victory, Sony has also gone about refreshing its entire range of laptops with Intel's latest Penryn 45nm processors. A Blu-ray writer and Penryn processor simply can't mask the disappointing battery life and high price.

Comment
NVIDIA GeForce 8600M GS: NVIDIA GeForce 8600M GS is the DirectX 10 capable successor of the GeForce Go 7600 / 7700 for laptops and technically a higher clocked 8400M GT. The performance is slightly above the 7600 / 7700 and, therefore, it can represent DirectX9 games fluently. For DirectX 10 effects, the power of the card is not sufficient.
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.
T8300: The Intel Core 2 Duo T8300 was at the time of announcement a fast dual-core CPU for laptops with 3 MB level 2 cache.» Further information can be found in our Comparison of Mobile Processsors.
