The first thing I see is the badly designed keyboard.

The legends have insufficient contrast and quite a number of them are too small to read. The legends for ², ³, home, end, page up, page down, return, control, num lock and the four arrows are wrong, or in the case of escape, do not fit the theme. Minus and underscore are indistinguishable from each other. The small letter g has the wrong font weight. The level 3 and 4 legends are incongruent with /usr/share/X11/xkb/symbols/eu. Despite level 3 and 4 legends, there is no level 3 shift key. The return key is misshapen and the escape key has a grotesquely large size. The place of the insert key is usurped by the fn key.

I would behoove the designer to pay attention to ISO 9995 and verify the result with users before sending it off to manufacturing, the company could have avoided a lot of trouble.
