I recently watch a young lady switch the Wii keyboard from QWERTY to a 9-digit telephone keypad, because it was easier. At least the letters are in a predictable pattern (ABC1, DEF2, etc.).
Dvorak keyboard layout (patented in 1936).
Perhaps it is the patent that prevents its adoption. I keep asking - why does Apple not give the Dvorak keyboard option to the iOS devices. With their innovation in keyboards (touch screen) the layout is all software, no hardware cost to switching the keyboard layout.
Yet we still teach and use the inferior QWERTY keyboard. We resist changing to a new system even when it would make our lives easier, more efficient. I think the keyboard will die a slow - very slow death. As computer become auditory and visual input devices. But the new touch screens - a tactical input device will still be around for quite some time.
