My issue is with the keyboard itself:
1. There need to be spaces between the F buttons (F4 and F5 and then F8 and F9)
I really didn't need such a big ESC key or and extra emoticon key - 2 spaces between the function keys would have been much better decision.
Making an endless row of keys is very inconvenient - sadly I screwed myself with this keyboard already .

Also the context key in the top right corner is bad idea - there was enough space in the bottom to put it on his normal place between the right ctrl + alt
