The problem with that - the same problem layouts like Dvorak have but worse - is that I sometimes have to use other computers. Any custom layout will be great for me - once I put forth the effort to learn it of course, but since it will only be for me nobody else can use my computer (This computer I'm using now I don't care as only I touch it). However I have computers that others in my family also use, computers at work where sometimes I share a keyboard. All of that becomes impossible and that negative is greater than any potential benefit.
