I got the accessory kit with the wrist rests and slanting mechanism at the same time as the keyboard, so that part's not an issue. I got mine before I've started having wrist pain as a preventative measure. I'm 35 with weird genetic conditions regarding my joints, I don't need to exacerbate things.

I think the other piece of the puzzle is that a lot of people don't properly adjust their chair and/or monitor for good ergonomics either. Eye level with a monitor should be right about at the top of the screen. It takes a tiny bit of getting used to at first, but then you really start noticing how much less neck strain you have.
