That said, switching was a huge pain in the ass.... like horrible for the first two months, and i promised myself i'd keep typing in both. However, i eventually lost the ability to type in qwerty, after about two years, but i honestly don't care, i genuinely love Dvorak.
The biggest concern most people probably don't think about is keeping shortcuts like CTRL+X/C/V/S/F, which apple thankfully has a layout for "Dvorak-CMD-Qwerty." The shortcuts are very obviously put where they are so you can toggle them quickly. Many programs don't account for this layout, which is why I wrote an Intellij IDE key mapping for it: https://github.com/scoofy/Intellij-IDEA-Dvorak-QwertyCMD-key...
The layouts that i think don't get enough love, are the one-handed dvorak layouts designed for amputees.
The idea that, in the end, the author suggests yet another standard seems a bit absurd to me.
