Why use this?

Qwerty Keyboards were designed to prevent type writer jamming by making the most commonly used letters farther apart, as old typewriters would often become jammed when pressing adjacent keys rapidly due to the hammer like mechanisms.

The Dvorak Keyboard, designed by August Dvorak in 1936 was designed specifically for speed. It's been estimated that during an average 8 hour day, a typist's fingers will travel 16 miles on a QWERTY keyboard and only 1.6 on a Dvorak keyboard. Awkward strokes are avoided by having all the most commonly used letters on the home row.

While with the android, finger distance is already reduced, it can still make a difference and perhaps help you memorize the layout for a home computer keyboard. It may help to tape letters over the keys if you're still learning on a home computer.
