I don't think on the right side it matches either. From J if I move down I always hit between N and M. Actually, at least on my keyboard, I think that the right side is worse - I find myself in a position where my thumb is on the space bar, my middle finger and index finger do all of the typing, and my wrist constantly shifts to hit enter.
On the left side - if I hit Z with my ring finger. If I wanted to type ZERO, normally it would be Z(pinky) E(middle) R(index) O(right ring), but with this the easiest is to hit E and R with the index finger.
Anyway, doesn't make sense to have to hack around a layout whose only purpose was to key mechanics to not jam in typewriters.
Your hands and forearms should be hitting the keyboard at an angle, due to the way your elbows hang outside your shoulders. Don't bend the wrists to make your hands go perfectly vertical; that's a major RSI concern.
At that angle, the U/J/M and I/K/Comma rows, etc., should line up pretty well with the bending of your fingers. Same with E/S/Z and R/D/X. But Q/A/Z (how most people type) requires a completely unnatural bend!
