Every time I'm confronted with an alphabetical keyboard my brain malfunctions. It should be easy but I'll be on R or S looking for the T and spend 5 minutes scanning for it. Usually via remote with some crappy app trying to login or search and its on a big TV huge, usually people watching making the awkwardness even worse since everyone else can obviously see where the T is.
I am not native but I feel pleasure from using Dvorak and chatting with no need to look at keyboard. I am trying to spread acknowledgement about Dvorak among young folks and those who agreed to learn feel the same boost. The difference is unimaginable for those who already has some muscle memory for anything related to Qwerty such as Ctrl-C. So the difference is between creating the layout for touchtyping goals and creating the layout for any other ones.
