I've occasionally thought about trying the Dvorak keyboard layout to improve my writing speed. However, I wonder if the speed gain is really worth the initial learning curve.
I'm curious if anyone knows of studies that tested people switching from Querty to Dvorak. Specifically, how long does it take the average person to recover their previous speed, and how much does their speed improve overall?
I would also be interested in any anecdotal evidence by those who have made the switch (or attempted it and reverted back to Querty).
