I currently own a pair of DataHands I found on eBay. They are pretty unique items, and start quite a few conversations, but I don't find them very practical -- probably because I don't experience extreme RSI pain that necessitates their use. They are quite large. For instance, I could not bring them to a coffee shop (for more reasons than this) because the smallish tables wouldn't be able to accommodate my 15" mbp + the DataHands. The build quality feel a bit lacking. These guys don't have the build quality of, say, an iPhone -- and for a $1,500 keyboard (retail), I would have expected a bit more. Its a bit strange to move some of the lesser used fingers in certain directions without hitting other keys. I'm sure this could be fixed with a little practice, but moving my ring finger without moving my pinky and hitting another key was/is tough. Overall, they are unique and interesting to have on a desk and pretend I use them. But if unless you have serious RSI and these are your last resort, I would probably recommend another ergonomic keyboard.
