Actually, this is not a bad idea, especially given that the current lay-out of our keyboard is not particulaly logical to begin with. Our current lay-out was designed for manual typewritters to actually slow down our typing in order to prevent jamming. This is why the most commonly used vowels must all be typed with the left hand. As such, some typists now employ keyboards that are designed to optimize typing speed. It would therefore not be much of a stretch to have a keyboard for hunt and peck typists. Windows already contains software adaptors for different language lay-outs.

Alphabetical keyboards exists. Many child-keyboards are alphabetical, I remember seeing them as far back as '95
