It's a Kinesis Ergo, model Elan (Euro symbols model). I bought when I had big RSI problems a few years ago (I figured things were desperate when I dropped a pint of beer 'cos I could not hold on to it). It is wonderful - cannot recommend it more highly. Macro programmable, instant keyboard layout change between Dvorzak and QWERTY. I can type 10 times faster than I used to with less effort and fewer mistakes. I also touch type now as a result of learning how to use the key board properly from the tutorial that came with the unit. Diffficult to use for a few weeks, but suddenly it just clicked and I was flying. I am planning on going over to Dvorzak layout soon as being unemployed still, I have a fair amount of time on my hands (groan)
