Comment
Intel Graphics Media Accelerator (GMA) 950: Intel Graphics Media Accelerator 950 is an integrated (onboard) graphic chip on Mobile Intel 945GM chipset. It is a faster clocked version of the GMA 900 and supports no hardware T&L (Transform & Lightning) accelleration (which is required for some games).
Only older games can be played fluently with these graphics chips (if they were not too demanding). Shared memory graphic cores in this category got the advantage of less heat production and longer battery runtimes. For office, internet, image processing, and video editing tasks these graphics chips are still useable without any restrictions.

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.

11.1": This is a quite small display format for subnotebooks. However, most netbooks have an even tinier display. The advantage 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.

1.2 kg: This subnotebook is one of the most lightweight of all notebooks and can be carried very easily. There exist hardly any models in this extreme class of weight. 7-9 inch displays are normal for this class of weight.
