I have the Natural Keyboard 4000 and love it. They take some time to get used to.
>I tried to pick up Microsoft's Natural Keyboard a few years ago. Those are the wavy ones, supposedly more ergonomic. After a week of frustration I renamed it the Unnatural Keyboard and gave it away. (To Tom Piper, actually; he loved them).
