I have ordered the equipment end of November and have been until now completely satisfied; all mentioned by some reviewers shortcomings I can not confirm. I must say though that I make no great demands on the speed and resolution. Everything that I and many of computer users make runs, without hesitation. But today (02.20.2015) I read in the Süddeutsche Zeitung under the title "Integrated vulnerability" that the preinstalled Lenovo adware "Superfish" Also between secure connections - such as banking - on, which hackers can enter the computer. This is so serious for me, that I, abwerte the notebook that really deserved 5 star due to its price-performance ratio on a star. After massive protests there would no longer be played, according to Lenovo since January. So if you have a manufactured before that date device should check it and on the side [...] know if he is one of the persons concerned and the instructions (unfortunately only in English!) follow. Although I do not understand much of this matter, I have managed to solve the "Superfish" problem. My confidence in Lenovo, however badly damaged, so it does not jump around with customers!
