You are talking about a couple of different things. Touch typing means your fingers are trained to know where the keys are. You can type without having to look at the keyboard. Touch typing doesn't necessarily have to be fast typing. You can touch type slow or fast. Bottom line, anything which removes barriers to doing your job is better. the less you have to think about it, the better. Hitting the wrong keys is a bit of a distraction and having to look at the keyboard could be a small break in concentration. This is especially the case when it gets to the point of being annoying. Sometimes people prefer writing with pen and paper because the physicality of it, the slower pace of writing and not being able to delete your mistakes makes you think a bit more about what you are about to write and what you have already written. It would be interesting to write out a program with pen and paper and have that immediately be translated into digital. Maybe an E-ink editor. ;)
