I have switched to Dvorak only one year ago, after many decades of using QWERTY. I consider this as one of my best decisions and my only regret is that I have not tried to do this many years earlier, because I had wrongly feared that typing Dvorak on a keyboard with QWERTY inscriptions might be a hindrance. As many other posters have already said, the advantage of Dvorak is seldom a greater speed (and I needed a coup…
Did you have discomfort while typing on qwerty? That you noticed before trying Dvorak I mean.
After switching to Dvorak, even after only a few days and even if only significantly later I have reached and exceeded the previous typing speed, it already felt much easier to find by touch any key than it has ever felt on QWERTY, despite the fact that I have been using QWERTY since high school, for almost a half of century.
Now I enjoy typing and it feels effortlessly, which has never happened before.
So before trying Dvorak seriously, I was never concerned with the fact that the keyboard layout may be suboptimal. Only after the change the improvement has been obvious and I have realized that what I had been using previously had not been good enough.
Nevertheless, when someone wants to try another keyboard layout, an appropriate time must be chosen, when for a few days there is nothing that must be typed ASAP. During the first few days the drop in typing speed can be very large. The slow typing speed can be very frustrating and it is very difficult to resist the temptation of going back to the previous keyboard layout, for a normal typing speed.
