I am owner of Kinesis Freestyle Pro too. I bought the keyboard with a tilt kit and pads. I am using it with macbook and I must admit that mac layout could be better (option and command keys are too small). Besides that the keyboard itself takes a lot of space on my desk, it is really huge compared to other keyboards that I had (including The Code keyboard).

Split design is definitely a win, but I needed some time to get used to it. After about a month keyboard started to feel natural. To be honest I would like to see a medical research on using various keyboard types. Personally I don't feel much difference compared to typing on macbook. Most problems that I had with my wrists where always connected to using mouse.
