I just because great experience with Acer again opted for a model of the Acer family and long time no regrets. Unfortunately, it's now increasingly problems ... buttons no longer work as sdtmgh and thus the Notbook can be used only with on-screen keyboard or an additional external keyboard, which reduces mobility. Furthermore, the touchpad strong response problems and the volume control responds garnichtmehr. Will exchange the Notbook therefore in the near future against a model from a different manufacturer ...
