Reviews for the Sony VAIO VGN-SZ791N
Source: PC World
The 4-pound Sony VAIO VGN-SZ791N falls somewhere between a beefy ultraportable and an all-purpose laptop. The SZ791N's power is undeniable, but the keyboard and the mouse buttons raise questions about component quality. And considering Sony's $2500 asking price, we can't help but wish for a little more.

The VAIO VGN-SZ791N/X has a lot going for it. It delivers a top-of-the-line processor and plenty of RAM, a wealth of features, and great looks. The nearly $700 premium it costs over the similarly sized, similar-performing XPS M1330 makes the Dell system a better buy, but for the extra money, you get a more business oriented machine with hard drive protection and TPM circuitry.

When Sony kicked off its SZ series of ultraportables 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. The SZ791N becomes our new ultraportable Editors' Choice by delivering a combination of outstanding performance scores and long battery life.

Comment
NVIDIA GeForce 8400M GS: NVidia GeForce 8400M GS is the DirectX 10 capable successor of the GeForce Go 7400 for laptops and technologically a slower 8400M GT video card (because of the smaller 64 Bit memory bus).

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.
T9300:
The T9300 is a fast middle class dual core CPU for laptops and similar to the T9400 but with a lower FSB.

13.3": This is a common display format for subnotebooks. Netbooks, UMPC and some subnotebooks have tinier displays. Nevertheless, the majority of standard laptops has a higher format. The advantage of a small display is, that the subnotebook can be small dimensioned and can be carried easily. Further the small display needs few energy, which improves the battery runtime and in consequence the mobility. The disadvantage is that the reading of texts is a bit exhausting for the eyes, especially with high resolutions.» To find out how fine a display is, see our DPI List.
1.8 kg: These sub-notebooks weight less than the average of all notebooks, but represent a heavier class of weight among the sub-notebooks. 12 inch displays are normal for this class of weight.
