And no, the uTron doesn't count. Yeah it's split, but it's still staggered qwerty, which is dumb.
Not really. It has
symmetric staggering and thumb keys for Shift and Backspace.
If you take your time to compare symmetric row-staggering to the better common columnar layout, you will find that the columns for the middle, ring and pinky are very much the same except for the square keys being rotated differently. There is a bigger difference for the index fingers, but on the other hand they are more dexterous.
I haven't tried a µTron (Micro-TRON) myself, but I have heard that there should be some kind of built-in Dvorak support, or a version with Dvorak legends. Traditionally, all TRON keyboards have had some support for Dvorak.
However, it is very expensive.. and the keys are actually smaller than usual, which may not suit a male westerner with big hands.
