Have bought me the notebook for professional business use. Has everything you need. The case gives the impression of a "light version" - but is ok Sure there are optically stable device. But since I've been using it primarily to 60% in the office, that's a good Endscheidung. It is not used on building sites !! The screen does not reflect the keystroke is easy at boot can be heard briefly run the hard drive. I am satisfied and can only recommend the Nootebook. Have found, despite a long search no alternative. Will, however, soon replaced by Vista Windows 7, because "7" will be ready faster. This option, however, is given with the purchase.
