There's a post on Slashdot, entitled How Effective are Ergonomic Keyboards? I have been using an MS Natural Keyboard at work for a while now and a Trust Natural Keyboard at home for about 2 years, and I must say that it has helped. I can't go back. Now if only I could find a decent replacement for the good ol' mouse. Because even though I use a Logitech handshaped one, I still have neck and shoulder problems on some days. Oh well. Comes with the territory, I'm afraid.
