This is the type I have at work. Since I am a programmer I spend quite a bit of time typing. Now, this keyboard does relieve a lot of the pain I use to suffer from, but it does take a bit to get used to. The break in the keys feels comfortable after a while but for that first week or two your typing speed will be cut in half. So be prepared for that adjustment.
Of course, if you have the money then I would suggest one of these extreme keyboards. I use the word “extreme” because that accurately describes both the shape and the price. Personally $400 for a keyboard is a bit much for me, but hey, for you, it might be a steal! Richest People
