I hope this site is not short of bandwidth because I have a lot of answers to for those who think I’m delusional and they know more about this particular topic than I do.I couldn’t post my evidence earlier though because I didn’t bother to save it when I first investigated the DSK and so I have looked some of it up again.The Dvorak Simplified Keyboard: Forty Years of Frustration

This is the source of the following quotes until further notice.
The person who posted it on the internet originally assures me that I have his permission, as does anybody else , to reproduce it for non commercial purposes so long as he is credited which I did in my last previous comment.
These are only excerpts adequate imo to illustrate my position but I will go head to head on any point with anybody who wishes to do so.

Upon analysis, Dr. Dvorak found that the standard'' keyboard had several defects. These can be summarized as follows: • Hand overload: This occurs when more than one character has to be typed by the fingers of the same hand. The longer the string of characters that one or the other has to type without a brief rest period (provided by a letter being struck by the other hand), the slower and more uncertain the typing becomes. The fastest and easiest strokes occur for characters on the home (or finger rest) row and on opposite hands. During periods of hand overload, typing speed is drastically reduced, and errors are more likely to occur. The hand overload problem is highlighted by the fact that over 3,000 entire words are type by the left hand alone on the standard keyboard, with another 300 being typed only by the right hand. • Unbalanced finger loads: The standard keyboard overworks certain fingers and underworks others, all out of proportion to their capabilities (taking into account strength and dexterity of each finger). • Excess finger movement: Because of the way the characters are spread out over the keyboard, fingers must reach from and jump over the home row far too often. This results in much wasted motion and fatigue. Indeed, on the standard keyboard, the
home row’’ is not really a home row at all since only 32% of all typing is done there. The real home row is the third row from the bottom which accounts for over 50% of the work. This is why a typist’s hands may unconsciously hover over the third row instead of the home row (containing the letters asdfghjkl'') between strokes. • Awkward strokes: Obviously, some movement off of the home row would be required whatever the keyboard arrangement. However, on the standard keyboard, many high-frequency letter combinations are unnecessarily complex and difficult to execute (just try typing
December’’ or ``minimum pumpkin’’ without looking). These awkward stroking patterns account for many errors, and also tend to lower overall typing speed.
Research
After several years of intensive research, during which hundreds of keyboard arrangements were studied and rejected, Dr. Dvorak received a patent for his Dvorak Simplified Keyboard in 1932. The DSK solves the basic problems inherent in the standard keyboard

Vested interests
Let’s look at some of the problems that Dr. Dvorak encountered when he brought out his new keyboard. First, in 1932, the year his keyboard was patented, the country was in the depths of the Great Depression. The typewriter companies were almost broke; so, naturally, they didn’t take too kindly to an inventor coming to them and saying, If you put my keyboard on your typewriters, you will be able to do twice as much work with the same machine.'' The manufacturers took this to mean,
Oh, you mean we will sell half as many typewriters? Well, thank you very much. Don’t call us, we’ll call you.’’
This feeling was seemingly passed over to the typewriter dealers. If you went into a shop then (and in many cases even today) and asked for a typewriter with the DSK, they would almost always try to talk you out of it. The reasons were always similar:
• You would not be able to use any other machine.
• Nobody else uses the DSK, why should you?
• The standard keyboard is good enough. Typing speed is not really that important in comparison to the other skills necessary to office production. And, besides that, the world’s typing record is almost 150 w.p.m. on the standard. Isn’t that good enough?
• The Simplified Keyboard is not really any better, regardless of what anybody tells you.
Certainly it is easy to understand that the typewriter companies were concerned with what they would do with their current stock of machines if a change were made to the new keyboard.
They probably just felt they were protecting their investment.
In a letter from a typewriter head office to one of their branches, they pointed out that ``The Dvorak keyboard is not new … has not been commercially accepted by the public … for the reason that the present so-called standard keyboard has considerable merit and that typists for years have been taught the touch system on that keyboard. To introduce a keyboard with the alphabet keys rearranged in as radical a manner as the Dvorak keyboard would cause considerable confusion. … If a school trained its typists on the Dvorak keyboard, they would have difficulty in locating a position where the machines were in use equipped with that keyboard. … There is no definite evidence that the Dvorak keyboard will increase the speed of a typist regardless of statements to the contrary. Our most expert typists are able to write over 150 five-stroke words in a single minute, which means that they are able to hit over 750 keys in 60 seconds. A keyboard that is capable of being operated at that high rate of speed cannot be so badly arranged after all.’’
This is a pretty long comment but most of it is a copy and paste quote and so my key board is not yet overheated. lol
Barring acts of God or getting banned from this forum I will be back shortly with some more highlights from this magazine article.
