Well, dunno about the mouse, I only got the kbd + numpad as it was cheaper, plus I just Love my Death Adder, perfect size for my small hand claw grip.
What would you say about the mouse ? did it feel good, etc.. ? for the keyboard, I like it, typing on it is really nice, but I guess that once you have tested a better ergo, you don't look backward. I know I am happy to not have to deal with a keyboard a lot at work (the standard stuff), cause each time it's a pain in the ass to type onto.
