Lately I am getting pain in my left wrist (my WASD-ing hand) and by process of experimentation it seems like the soreness is coming from having to "break" my wrist to the outside (in the direction of my little finger). I understand this can lead to a condition called ulnar deviation, and as much time as I spend on computers by necessity and choice I have been worried for some time about developing carpal tunnel or related conditions.
Basically to relieve the soreness it seems like I need to be able to keep my wrist straight. The only way to do this for my left hand would be to rotate my whole keyboard clockwise, but then obviously my right wrist would have to "break" even worse to type. So I've started looking into ergonomic keyboards. Most of the ones on the market are cheap membrane crap like this and I am not willing to sacrifice the responsiveness of mechanical switches. The only mechanical ergonomic keyboards I have been able to find are the Kinesis Freestyle Edge (and its predecessors by Kinesis) and this model on Amazon, the Cloud Nine 989M.
I am leaning strongly towards the Freestyle Edge because I know Kinesis is at least an established company that's been around a while, whereas I have never heard of Cloud Nine before (no, they do not appear to be associated with the esports organization Cloud9), and I also prefer the more compact design of the Kinesis (I have been using TKL keyboards for some time). The only thing that gives me pause is that many reviews say that the "tenting" kit for the Kinesis is really a necessity, but they sell it separately for an extra $25 on top of $200 for the keyboard itself which kind of pisses me off. The Cloud Nine at least comes with tenting, albeit at a fixed angle.
So before I plunk out the cash: does anyone here have any personal experience with either of these products, especially the Freestyle Edge? Or are there any other ergo mechanical switch options I should be aware of?
I should mention my favorite switch type is Brown, I could maybe live with Reds and Blues are a non-starter.
