Why do you think that the keyboard is the problem, and not the indoctrination of "this is the right way to type and posture" leading to further stress?
In fact, in my admittedly small sample of others I know who do have problems with their wrists, they were all ones who tried very hard to rigidly conform to the "standard" posture and move only the fingers of the hands instead of the whole arm. They were also people who hit the keys much harder than necessary.
I use a standard flat QWERTY keyboard and I can type for hours at 150+ WPM with no problem, but I've had comments from some of those people above that I'm not doing it right... when they're the ones who are getting pains in their wrists, not me...
If you try to keep your hands parallel to the keyboard no matter what, you are going to stress your wrists. Let them approach at whatever angle feels comfortable, and relax. That also happens to be the "trick" to typing faster too --- if you expend effort on trying to be "strict" about posture rather than just hitting the keys in whatever you feel to be the most comfortable way, you'll tire quickly, type slower, and stress your joints more.
