What bothers me after some use of the C2 is the onscreen keyboards. My hands are not small, but in landscape, it is hard to reach the keys in the middle of the screen. There should be an option to make the onscreen-keyboards smaller with a large gap in the middle in landscape, and maybe also to make it smaller and move it to the lower right edge for usage with one hand in portrait mode.
Scaling the onboard-Keyboard together with the rest of the screen makes no sense on such a large device.
EDIT: I found the option to split the keyboard in Landscape mode, that helps a lot, but I still think that there is potential to gain more screen space with a more compact keyboard. Almost 50% of the tablet is used up by the keyboard in landscape
