I just purchased this keyboard and mouse. I haven't used the mouse yet because it hasn't charged, but the keyboard is sweet.
My only complaint so far is that it isn't a natural keyboard like my old M$ one and I'm having a little trouble getting used to the new hand position. I keep typing gibberish.
The function keys are awesome - way better than the M$ function keys. And I can type (almost) effortlessly from WAY OVER HERE!!
NOT ONLY THAT, I CAN ALSO TURN UP THE MUSIC FROM WAY OVER HERE SO I HAVE TO SHOUT EVEN LOUDER.
UPDATE Mouse is great as well.
