After I had all Acer programs removed, the buttons worked perfectly on the tablet, and the keyboard is running since without problems.
Now for the rest:
The hardware is decent for the price. Yes, the tablet tilts backwards when choosing the angle of inclination in connection with the Tastaturdock too high. But it was known to me and I had prepared myself. If you normally sitting at a desk, do not experience this problem.
The display is super, I can see no backlight bleeding, and the brightness is very good. The display reflects strongly, but that's in this price range simply normal.
Windows 8.1 runs fast, and thanks to the low resolution (WXGA) you have to adjust also no display scaling in Windows (so it stays at 100%). This helps especially older applications that implement the scaling is not good.
My field of application:
Surfing, office (yes with it) create and a few small applications with Visual Studio 2013. But enough of the Intel Atom processor loose.
If one disregards the teething problems, the switch 10 a recommendation is well worth it! I'll keep it definitively. Because if only the great display and the keyboard acceptable justify the price. Maybe Acer brings soon a software update that eliminates the more recent problems.
