I actually have one as well, the 1.0 model (also black on black keycaps, Cherry MX Red switches) and love it myself... even though it took about a month before I finally adjusted to how light the Cherry MX Red switches are.
For me personally though, I do most gaming with a controller these days, and so the keyboard is actually my primary desk keyboard, only very rarely used for Bluetooth to my media PC. Still, I appreciate the option to be able to just switch to any Bluetooth device whenever I want.
Most of the extra functions are silly, and I would rather they were removed. And the font on the keys is hideous. That was my primary motivation for the black on black keys, you never have to look at how horrible and unprofessional it is.
Still, I really like the keyboard too.
