The point (and the patent) of the Smartboard is that keys are aligned to finger movement, not to the mechanical needs of the original, mechanical typewriters from a century ago.
What's the problem?
Get a standard keyboard (straight or 'natural' doesn't matter). Put your fingers into the touch-type starting position ASDF JKL:
Move your right middle finger up one row. You're on the I key now, only a bit to the right of the key center.
Now move your left middle finger up one row, again without any sideways movement. You're exactly inbetween E and R now.
This is what the smartboard fixes - key rows aren't all left slanted, but instead fanning out to match how each hand's fingers open up and curl down. This minimizes sideways motion (except for index finger and pinkie, obviously), and drastically improves your typing speed. The drawback is, you'll soon notice how awful the standard layout actually is, and you're going to buy more of the smartboards.
The smartboard still exists as a product - USB only now, PC or Mac version.
