The keyboard is the greatest invention ever! After spending two months by myself working on Microsoft Natural 4, I found that I was unable to switch back to using my regular keyboard when I returned to work. I had to acquire MS Ergonomic. I preferred it to the "four," as it was created to be clearer and more concise, and the key travel was about average and quite gentle. The push on the spacebar is very close to becoming flawless. In an unusual move, the numlock button has been relocated from the numeric keypad. I would say that, in overall, I am extremely satisfied.
