Did you feel the weight of this keyboard? This thing is heavier than general keyboards. Typing is easier than before, too. I installed the gaming keys and they have a rugged feel to them. I like the red color. I have the cherry/black design. What did you get? I also don't see any driver installations for this.
I didn't know cherry mx black were an option on this keyboard. My model has the cherry mx red switches (no tactile feedback or click) and I bought some key dampeners to reduce the noise of bottoming out. (It took me 2 hours to put key dampeners on both my keyboards

) I used to use the gaming keys on my K60 for a year and I really liked the feel but they just started to get in the way of regular typing and so I've stuck with the standard keys. You don't need any drivers to use the keyboard, it's got everything it needs built in and just operates as a USB keyboard as far as your computer is concerned.
You can do some real silly stuff with programming the backlight. There's also a switch on the back that's labeled bios. I forgot what it does, but I know that the one time I accidentally changed it I couldn't figure out what I did wrong. I've got it set to "1" and I think that's the default setting.
