Dvorak is great!
I put in a little time to learn Dvorak, and through a kind benefactor was able to get my hands on a Typematrix keyboard, and the combination is wonderful. What I notice most of all about the new layout is the amount that my fingers remain on the home row. I am not continually reaching across the keyboard, especially with the dreaded pinky reach. With the Typematrix, there are additional benefits, namely the small size, gentle feel, and backspace and enter keys in the middle. It is a very clever design, and I don't want to use anything else.
If you want to learn more about the Dvorak keyboard, on which I typed the whole blog post with nary an error, go to DVZine.org.
