I personally think qwerty is the only way to fly...I am extremely fast on it. I have tried to type several times on my wife's suretype keypad and I just have so much difficulty on it...I think the secret to that type of keyboard is to not look at the screen while you type and just trust that it will figure out what you intend to type.
If you don't have any real attachment to a qwerty, I hear that the suretype is pretty easy to learn. I know that it hasn't taken my wife that long and she can bang away on that thing now with the best of them!
