I ordered 2 months ago about my Lenovo Note Bock (i7 processor and without an operating system). The delivery was quick and easy, the package has a stable and protective impression. Since I'm free as a student on the university's website to a Windows operating system and offering 2 months ago was even better (I then about 430 or 440 paid) I've made a real bargain. With the performance I am very satisfied, it may require the computer programs and the more power, as in my CAD programs to easily and run smoothly. If you do not intend with this notebook any high end graphic games to play, but to work in the first place, then this computer is always enough. A bit annoying is, as already mentioned, the reflective display, thus you have to adjust the screen brightness up what shorter battery life means. But that is only a small flaw, but I draw from no star.
