Since I am still used from DOS times to copy with Ctrl + Ins and insert with SHIFT + Ins I can with the Comfort Curve not work useful because twice the Entf- (Delete) button to place the Insert key equal mitbelegt. What good is that?
In addition, other keys are still been rearranged (eg right Windows key) and generally you get the feeling the keys would be contrary to an ordinary keyboard a little "slip". This finds expression in numerous typos when switching between keyboards.
