So far I am very happy with my decision. The most important thing was to me the screen. I wanted one that is easily readable even in light irradiation. That's why I've got me for the dull non-touch version chosen. The display is really great. It is not as good as non-reflective with my old HP EliteBook, but also reflects hardly. The picture is so sharp that you can work well with Full HD on Windows desktop without the need to resize the icons / fonts. Which are then relatively small but legible.
The keyboard was also very important to me. The Hub is certainly not as with a Lenovo keyboard, but still very well usable. It is a bit like the keyboard of the Apple Air. You can write very fluently.
Getting used to the touchpad without separate keys. "Select and drag" in particular is very fiddly. That does not mean that the pad is bad, but it just lacks the keys. Since it depends then quickly turn a mouse.
The commissioning / installation is a long endeavor. Up to the bloatware uninstalled updates, Windows 8.1, ... has installed some time passes. Meanwhile the fan rushes neatly. If, however, then everything is installed and the Index Service is completed, the device is silent again.
The referenced wifi problem I could not discover. The range is no different as with my old laptop (Den I had with current wireless card retrofitted). Possibly was the now resolved through driver updates. I would have liked 802.11ac. But everything can not halt have ;-)).
Fascinating to the device is really its amazingly low weight. Together with the very fast startup are the outstanding handling. You look at it, work on it and you can get started. You can hold it loosely with one hand and with the 2nd tap without you park it.
I have now started to test any benchmarks about the speed. It's just all so fast that I have no waiting. Since I do not play with it enough for me of the Core i5 completely.
So everyone is considering: buy recommendation!
