I was introduced to this general "type" of keyboard at a Med. Transcriptionists conference a few years ago. That keyboard was still different from this, but the woman who had it raved about it. When I found this one I had to try it out and OMG - the world of difference in ease of use and comfort was amazing - even from the first kinds of ergo boards. This one allows for the user to not only hold their hands in a much more natural overall position, but with the keys falling slightly downwards towards the back of the board, rather than upwards, everything is much more comfy. It didn't take long to get used to either. Once you get used to this keyboard style, you will not willingly go back to other boards.... they actually hurt you to use them. I have short fingers and still the number keys are not difficult to reach. Top notch keyboard no matter how you look at it. (When I have to use a laptop in another room or while on vacation - I take this keyboard with and just plug it in to that and wholla... I am a happy camper).
