###### DVORAK

1. QWERTY was designed for the typewriter, not the typist.			Src: http://workawesome.com
Christopher Sholes, who invented the typewriter, found that early prototypes of his invention had a mechanical flaw: When he struck neighboring keys in rapid succession, the typewriter jammed. He needed to replace the initial alphabetical layout with one that separated keys often struck successively. Thus the QWERTY layout was born. This did not solve the problem entirely, but it made the machine jam a lot less. Good for the typewriter. But what about the typist? While QWERTY was designed so that the typewriter could work, Dvorak was designed so that the typist could work well.
2. Dvorak increases your speed.
Typists base their fingers on the home row of the keyboard. If you want to increase typing speed, the home row is where you place the most commonly typed keys. This is exactly what Dr. Dvorak did in his layout — 70% of keystrokes are on the home row; 22% on the top row; 8% on the bottom.
In QWERTY, only 32% of keystrokes are on the home row. Which means most of the time, typists’ fingers are either reaching up for the top row (52%) or down for the bottom row (16%). So not only does QWERTY do nothing for typists, it actually hinders them.
Dvorak further increases typing speed by placing all vowels on the left side of the home row, and the most commonly used consonants on the right side. This guarantees that most of your strokes alternate between a finger on your right hand (consonant) and a finger on your left (vowel). Alternating between fingers from either hand is faster — just imagine texting with one hand or drumming with one stick.
