I've been using Microsoft Natural keyboards for 20 years now. I used to suffer terribly with RSI from years of typing on crappy keyboards, with bad posture and not enough breaks. The Microsoft Natural keyboard has been good to me - I haven't had RSI twinges for 10 years or so now! I'm typing this on a Microsoft Natural Keyboard Pro which Wikipedia says was introduced in June 1999 - round about the time I got it. I wish it wasn't white as it really shows the dirt, but the media buttons are the best! I've got two and I switched to the backup recently as my main one got really dirty and I haven't had time to clean it. The MS Natural 4000 is very good too - I had one of those at work for over 10 years. I did wear the legends off but hey - who needs to see what key you are pressing anyway! Just don't press F-lock by accident as you'll be wondering for ages why your function keys aren't working. I like the front stand of the 4000 to put the keyboard up a bit at the front. It is very good for encouraging good posture. (The other thing I did to help with RSI is switch hands with the mouse. It took quite a long time to get used to using the mouse with the left hand but it really made a difference as my right wrist was worse than my left wrist. I'm now ambidextrous with the mouse - the only thing I can't do is draw with the mouse with my left hand!)
