Second question - in this day and age of easy connectors, why are numpads attached to the side of keyboards? What do left handed people do? Or people who don't use the numpad? Why not have the numpad detachable? Same goes for the arrow keys.
It's beyond me why the "Z with little finger" technique is so widespread. It's universally taught, yet you're obviously bending your fingers in an uncomfortable and unnatural direction when you go to press the bottom row.
No one's complaining about the staggered layout of the right-hand keys, because it matches how your fingers bend. Staggering is great when it matches the natural angle of your fingers on the keyboard.
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.
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!
