Back when I had to learn touch typing (do they do that any more?), we learned the 'correct' finger for each key. The five columns of letters on the left belong to the left hand, so the "B" is in the correct place. The "6", however, is on the left of the split, while it belongs to the right index finger. Most split keyboards get this 'wrong' -- in the sense that old people like me who learned to "touch type" will have to re-learn it. The root cause of all this disagreement, of course, is the weird offsets of the rows. Why aren't the keys in a square matrix formation? There haven't been typebars on keyboards in decades, and the fingers on my left and right hands are symmetric. If you're going to make everybody learn new muscle memory for escape, space, arrow keys, function keys, etc., why not fix the row spacing, too, while you're at it? I find it strange to maintain just this one legacy misfeature.
