Its The Worlds Best RSI Keyboard, And You Cant Buy It:
http://www.emailbattles.com/2006/04/24/other_aadehidhca_ia/My favorite ergonomic keyboard is the long-discontinued (it was originally released in 1993) ergoLogic/Key Tronic FlexPro - the way you can click the inner sides of the split space bar when angling the keyboard feels natural/comfortable and was just ingenious. I love the fact that you can customize the actual angles of the keyboard halves with so much flexibility (I used it cranked all the way up). It was fairly trivial to change it to a "flat" keyboard if someone needed to use my computer. The fully adjustable palm-rests shown on the bottom keyboard in the photo (they adjust not just left/right, but in height) are great, but they're probably not mandatory. The only thing I hate is the wobbliness of the raised platforms, which is particularly lousy/annoying for gaming; I'm an avid WoW player, which is why I have a "new" FlexPro sitting in a box instead of at my desk.
The beige color is dated (although I hate black keyboards as IMHO they look cheap and show dust too much), but I love the dark metallic gray you use on the QFR with Cherry MX Blues - hint, hint.
I personally enjoy the crispness of white LED back-lighting, but I'll admit it's not a priority in an ergonomic keyboard - especially if it drives up the price. For me, what is more important than lighting is that the keyboard doesn't wind up with ugly, semi-worn off key cap lettering - which is already becoming an eyesore on my QFR, and it's less than four months old.
No it doesn't affect functionality, but it looks like heck when you aren't actually typing, and it's shameful that it's happening on a pricier keyboard. If CM can't improve the durability of the key cap print, offering the keyboard in a "stealth" version would make that a moot point (I suddenly find a back-lit "stealth" keyboard a REALLY intriguing concept, lol). Also please consider offering a longer, braided USB cable - the one on my QFR could stand to be at least 6-8" longer. Or at least pretty please offer longer braided cables "after market". I know I can buy any old micro usb cable, but once you use braided cables it's tough to go back and extension cables seem to cause issues.
If something with the same functionality as my beloved FlexPro (ability to set custom keyboard angle and the dual space-bar activation functionality) could be designed in a physically split, matrix layout, tenkeyless option (ability to buy a coordinating mechanical keypad that isn't a financial rip-off would rock) with cherry mx browns or reds and soft o-rings..../drools. Heck, if you can create a knock off that eliminates the wobbles and uses your metallic gray finish, with an update to PS2/USB, I'd still buy one in a heartbeat - even if it was a crappy membrane keyboard.
Media keys, or at least volume up/down/mute would be a bonus but are not a dealbreaker. At least one USB port (preferably 2) would be terrific. I don't know why they aren't the standard for EVERY wired keyboard.
If you're curious about the FlexPro's spacebar or the keyboard in general, I'll loan you mine if you pay for shipping and promise to send it back. The Flex Pro wasn't a financial success, but it originally retailed for $400, which most people would be loathe to pay even now. Ergonomics (and "different" keyboard designs) were a much tougher sell back then, as were expensive keyboards in general.
