I use a Kinesis Advantage. I have two of them actually, one for home use, and the other as at the office. I honestly would not have a job without them. I <i>destroyed</i> my wrists on that crappy Apple keyboard. It&#x27;s awful for your wrists and gave me crippling RSI. If I use a laptop for more than an hour or two, I&#x27;m going to be feeling it later.<p>I&#x27;ve never tried the datahand. I&#x27;d love to but, my understanding is that they&#x27;re super hard to find and very expensive. Also, there&#x27;s a stigma that goes with weird looking keyboards. I always get comments about mine. People definitely prefer aesthetics over preventing an RSI.<p>Developers, protect your hands and wrists and get a GOOD keyboard.
