Ergonomic Mechanical-Switch Keyboard?
dotancohen writes "As wear and tear on my hands builds up, I find that I need an ergonomic (split) keyboard. It seems the vast majority of available ergonomic models are either crippled with dome-switches or have unusual designs, which place many critical keys under the thumbs (I cannot use my right thumb). The one normal-appearing contender, the Northgate Ergonomic Evolution, seems to be noisier than even the Model M — in fact, it echoes! Programmers and hobbyists geeky enough to be here today: what do you type on?"
I hate to point you elsewhere rather than provide an answer, but the GeekHack forum is a very rich source of information and reviews from people who know what to look for in a keyboard (or any input device), and they've probably reviewed every keyboard out there (and modified them). I don't use ergonomic keyboards, but I am very adamant about mechanical-switch keyboards that have just the right amount of tension and tactile/audible response.

There are also some interesting vertical keyboards like the SafeType and the Kinesis Freestyle Ascent, but they're kinda expensive and might take a bit of relearning.
Here's a survey of ergonomic keyboards: http://nsx.underbase.org/db/kbd/keyboard-survey.htm
Personally I use a DSI ASK-6600 and a Scorpius M10, and I like them both very much. The DSI keys need a bit more force to push, and it has the large "Enter" key I like from old Keytronix keyboards (as opposed to a large Backspace key and a repositioned backslash character, like the Scorpius and Model M have).
These two keyboards probably don't appeal to you because they're not curved/natural keyboards. I avoid wrist problems while using a regular (straight) keyboard because I have a custom typing style, wherein my wrists are not angled when they rest on my "home row" (e.g. index fingers rest on V and N instead of F and J). This limits my upper bound of typing a bit (under 100wpm), but fast continuous typing will only get you so far in programming and sysadmin work, whereas wrists that don't hurt are quite nice... I also remap my CapsLock key to be another Ctrl, for easy one-handed reach to Ctrl+F1-F5/etc.
While you're at it -- upgrade your mouse too! I found all my wrist problems went away when I moved to a Logitech Cordless Trackman (wish it was corded, but whatever). This has a finger-operated trackball and a thumb-operated left-click, which I find MUCH more accurate and comfortable than a thumb-operated trackball (e.g. most trackball mice on the market now). Trackball mice are usually considered to be more accurate than regular mice anyways. One of the big benefits here is the fact that your wrist isn't as twisted as with a regular mouse... if that's your main goal, there are also some expensive ergonomic vertical mice that might be comfortable.
Ergonomic Model Ms exist, but are incredibly hard to find. You may want to ask around, though. An old workplace of mine had one sitting around in the storage.

i know this is going to sound strange - you asked one question but get an answer to another, but the root cause of the problem isn't the keyboard, it's the fact that you're hunched over it, tensed up, locking out the blood supply from your arms and screwing up your hands.
to fix that, you should AT LEAST be doing the overarm stretch: stick hand straight up, bend elbow so that hand goes behind head with elbow still up in air, then take other hand onto elbow, pull and lean geeeently sideways so that entire side stretches
you should also be doing "horse stance" from tai-ji, which is really quite complex to describe, but imagine that you're sat on a horse: your legs are apart, knees bent, and hands outstretched imagine holding reins _but_, the actual tai-ji "horse stance" has some quite complex and specific positions and purpose. the primary purpose is to stretch tendons on the *underside* of your arms and in fingers (forearms as well) as well as elevating the heart-rate.
so, you have to push your elbows outwards so that your upper arms are 45 degrees from vertical, but forearms are absolutely horizontal. hands you have to imagine that you are holding two basket-balls, one in each, palms down but slightly elevated a fraction, fingers splayed as far wide as you can go.
get it right and you should feel loots of tendons stretching under your armpits, at your elbow-forearm _and_ wrists _and_ the thumb and little finger tendons! and that's exactly what you need - to stretch out that which you've utterly cramped out and damaged.
the horse-stance itself results in quite seriously elevated heart rate: you're bending your knees and staying there, so you should be breathing deeply and fully. stay there for as long as possible, increase until you get to 5 minutes. you will be surprised: horse stance for 5 minutes is one hell of a long time.
the other one is the yoga position where you sit on the floor, put one leg bent into your crotch and the other straight out, then lean over and grab ankle (or as close as you can get it). with each breath out, go down a little further. DO NOT "shake". if you feel yourself shaking, BACK OFF.
what i do with this yoga position is, rather than stay going down straight is i roll _sideways_ after a while, so that i get more stretch on the insides of my arms and side, which is exactly where you need the circulation increased, to get bloodflow back to your arms and fingers. repeat on the other side but come up SLOWLY - don't just try to jolt yourself out because you _will_ pull a muscle that way, especially at full stretch.
all of these exercises are designed to increase the circulation on the _underside_ of your arms (at the top) as it's here which is actually causing the blood flow to decrease, toxins to build up, tension to happen and damage to occur.
so - yeah. fuck the keyboard - get your health sorted out.
