When I was a kid I fell hard on my right wrist and since then I always get wrist pains when angling my wrist very high up (ie: when using a very high shaped mouse or doing push ups).

So I have narrowed down my choices for a keyboard to the following 2:

Microsoft Natural 4000:

And the Razer Arctosa:

The Razer is a slim type keyboard similar to a laptop feel and the hand-rest would help with keeping my hands straight with respect to my forearms. I am more inclined on getting the razer but am not sure if this will benefit my wrists in the long run.

Any thoughts on this would be greatly appreciated.

Thanks.
