After some time this noble instrument was in use now, I can say about the features more. First, very briefly: value for money is hard to beat in my eyes. Power: The computer is very nimble. The start time for Windows is usually 15 seconds to the login screen and another 15-20 seconds until final starting. Compared with some other devices that I use as or used, is the top. Graphics editing and music editor are possible, but drive the machine to its limits (see also :) Noise: The device is to name paraktisch silently. The fan starts only in extreme cases, to a little more, but really should not happen on such a computer for your daily work. Hard drive is with me practically inaudible as well as usually not in operation. I upgraded to 2GB of memory and - contrary to all advice of experts - the Windows swap file disabled. After starting my essential programs like e-mail, Internet, database, text and tables almost never takes place a disk access. It still remains enough memory (measurements: less than one disk access per minute; approximately 1 GB of memory remain permanently available.) Battery life: My mode is always set to "Automatic power selection", camera and Bluetooth are traveling off. In order for a term of up to 4.5 hours is possible. But is also related to the above-mentioned memory upgrade. Tip: during the day does not go down even during long breaks alike. Standby is so efficient that a reconnection consumes more energy practical. My computer is actually the whole day and goes on the road just in standby. Equipment / processing: Metal surface metal just looks classy and is also very resistant. Does make a difference to the standard version - if you pay attention to something. Only the keyboard bounces sometimes for something. Personally, I'm splendidly cope with the small keys after a short training. And: Weight with just over a 1-kg simply unbeatable on the go. Overall rating: Strong buy recommendation, has so far found no grounds for exclusion.
