I disagree with his/her keyboard of choice. I find the ergonomic split keyboard to be vastly superior. I get noticeable wrist strain after a few hours at a straight keyboard. The Microsoft Natural Ergonomic 4000 or the Microsoft Natural Wireless Ergonomic 7000 are the best I've tried. Also, leaning back in the chair (130 degrees) with elbows out is much easier on me than sitting straight up. But anytime ergonomics comes up, size of the individual matters. I'm 6'2" and 190lbs with large hands. My wife doesn't like my my keyboard because it is too large.
