The Qwerty keyboard layout (named so because of 
        the first 6 upper-left keys) is perhaps the most ancient aspect of today's 
        computers. The current arrangement of letters is actually designed to 
        slow one's typing, a holdover from the days of mechanical typewriters 
        whose keys would jam if pressed in quick succession. Rumor also has it 
        that the arrangement was partially designed to help typewriter salesmen 
        demo the machines by placing all of the letters in the word "typewriter" 
        in the top row (take a look for yourself).
        
        The Dvorak (pronounced "duh-VOR-ack") 
        layout was scientifically developed in the 1920's to place to most 
        commonly used letters (in English) on the home row, to reduce the distance 
        that the average typist's fingers have to travel, and to more evenly distribute 
        the work load between left and right hands. The layout never took over 
        the typing world as some hoped. The reasons are many, but partially it 
        was due to the difficulty of physically changing existing typewriters 
        over and partially due to having to retrain existing touch-typists. It's 
        unknown today how many people use the Dvorak layout. The replacement of 
        the typewriter by the personal computer meant that one can change the 
        letters produced by one's keyboard easily and instantly.
        
        Dvorak has been built into Windows since version 
        3.0, Apple's MacOS since version 8.5, and Unixes (ie. Linux, BSD, Solaris, 
        etc.) since forever. You can also switch DOS, older versions of MacOS, 
        and pretty much anything else to Dvorak. See the links below for instructions 
        on how.
      
I taught myself to use Dvorak in early 1995 
          because of the onset of RSI. A friend 
          had been using it since he was a fetus and loved it. I found that after 
          practicing for a few days I could touch-type quite easily. Dvorak is 
          much easier to learn than Qwerty because the keys arranged sanely, vowels 
          under the left hand, common consonants under the right, instead of being 
          randomly arranged as in Qwerty. The only difficult aspect of learning 
          Dvorak was switching between Qwerty and Dvorak. It's very similar to 
          speaking two languages and having to switch back and forth between them. 
          I found it took a couple of months to be able to switch back and forth 
          without speed loss and a year or so to be able to do without thinking.
          
          The pain in my wrists is gone these days. I attribute 
          this partly to better typing posture and partly to a better keyboard 
          layout. I've found that I can typing significantly faster using Dvorak 
          with much less effort (since my fingers spend much more time on the 
          home row). Additionally it keeps co-workers, roommates, and little brothers 
          from commandeering my computer, especially if there is a password (try 
          typing a password on a keyboard where the letters don't match the keys).
