Query: Excellent key "touch", solid mouse

I'm a tax accountant and do a lot of keyboarding, so I needed a keyboard that I could use for extended periods without tiring my wrists or fingers. This keyboard is unbelievably comfortable, with exactly the right level of tactile response and with keys that are spaced to reduce the chance of hitting the wrong key if you are "touch typing". It has made me much more efficient and less tired during long stretches of work. The mouse is equally well-designed, with a responsive scroll wheel and perfectly curved shape to fit my hand without straining. The mouse is heavy, but so well balanced that I rarely have to pick it up. The furthest I move the keyboard from the transmitter is about 4 feet, so I can't speak to its long-distance capabilities, but in the 6 weeks that I've used this set I have never felt any wrist or hand strain, which makes it perfect as far as I'm concerned.
