... With two construction-related cardinal errors: one can accidentally touch the palm of your hand when holding the display in landscape mode the power switch so that the machine runs suddenly down. That is total crap. But by design, because the switch button is located on the housing bottom. Second, there is only one micro-USB port, which also serves as charging the battery. One can therefore not an example via a USB hub at the same time when charging or connecting multiple USB keys or mouse to the device. During charging, so you are reliant on the touch pad or the touch screen. This is not optimal, because the touchpad is quite small and not always as responsive as it should be. In this respect, a separate power connection or a second USB port would be helpful. Next I have to complain about the use of the function keys on the keyboard cover. The F keys 1 through F 12 may only be used while holding down the function key (Fn). In "normal" keyboards can reach the F-keys with simple pressure. Also based on double occupancy, I know it so that the Fn key has to be pressed only for special functions. Here the situation is reversed. Apart from these "quirks" you can not complain. The display is crisp and clear and easy to read with an antireflection film even in bright sunlight. The touch screen responds in Tiles mode precise. And the best: in fact the battery lasts in mixed operation by 8 to 12 hours at a stretch. Of other comparable Convertibles can cut slice ne ...
Update 2/27/2015: The big battery has one drawback: the charging time! Based on a residual battery capacity of 30% takes to load with the supplied charger 8 hours or more.

This only 3 instead of the previous 4 stars.
Update 20/03/2015: At the same time charging and connecting a USB hub with a Y-cable is not possible. Probably the pins for the power supply are not activated in the Y-cable.
