That was similar to my experience with Dvorak, back in the early 90's. Having learned touch typing on qwerty on an IBM typewriter from high school, and learning/typing for several years, I thought I was pretty good typist, but in college, I had the nagging feeling I wanted to try something else, since my wrist didn't feel too good after a long typing session, and I wanted to get even faster.<p>It felt so weird learning to type in Dvorak layout, but I got used to it and after a month, I was typing ok, and within 2 months, I was probably typing the fastest I've ever been. It felt much easier to type physically and felt more effortless to type. The downside was that every time I went to type on someone else's computer, I just couldn't type on qwerty anymore. Some people just seem to have knack on being able to switch between layouts, but I just couldn't. Being an "expert" on computer as a software engineer, imagine people's surprise when I could barely locate a key... "So where is that B key again?" Also I couldn't use VIM no matter how I tried to remap the keys in vim. Eventually, I abandoned Dvorak for practical reason, and when I did, it took few weeks to get back to re-learning qwerty.
