Convenient typing, choosing the color of the backlight is not a gimmick. In the darkness, it is well to distinguish the keys. The 8 colored metal buttons is a useless gadget. marking the letters is less readable because the backlight is suitable for black keys and not light gray. The wheel noise is a gimmick because it takes too much movement of the index to go from 0 to 100%. A cursor would be better.
The small control panel is a real plus. We must learn to program it and choose information based on need. I also really like the command that disables the Windows key stupidly placed between Ctrl and Alt. What is the idiot who decided to place such an order there, so that his place is on the side of F12?
