Really stands out is the almost nonexistent heat development, even after prolonged use of notebooks. It's the same with a barely perceptible operating noise!
The Windows Experience Index assesses the major system components of the notebook as follows (on a scale from 1.0 to 7.9 - the latter being the highest rating value concerns):
1. Processor 5.5
2. Memory 5.5
3. Graphics (Windows Aero) 4.5
4. Graphics (3-D Games) 5.9
5. Hard disk (data transfer rate) 5.4
At first I used the pre-installed Vista as Bertiebssystem, the notebook ran including fast and stable. Then I, however, chose to upgrade to Windows 7 (for 19,00 at Samsung ordered). After upgrading the function keys no longer worked as well as the Wi-Fi feature - the driver is obtained, however, on the Samsung download page. After installtion of these drivers (Easy_Display_Manager_3.0.3.8 & Wireless_LAN_Realtek_32bit_1676.1.0622.2009) everything runs again as desired and smoothly!
For the price, there are in my view only a few real alternatives, also in terms of the quality of workmanship! I would buy the notebook at any time!
