The device in itself is fine. Unfortunately it broke down early and the service from Asus is an absolute outrage. In less than eight months the SSD gave up the ghost. The unit was posted under the warranty services and swapped the SSD. Unfortunately, the repaired device initially came too late because Asus wrote the wrong address on the package. I then realized that not Windows 8, but Windows 7 has been installed. Because I need the device strongly in their daily work, I asked for the service. There they told me that I must return the Ultrabook again, should I install Windows 8 by hand, I would I lose the warranty. When I held up the service staff that is legally hardly tenable, ended this without a word the call. In the evening I then realized yet that the defective 256GB HD has been replaced by the model with 128GB. When I complain in this matter I have not yet received any response. I'm speechless. That was certainly the last Asus product I've bought.
