I used some random type tutor software in high school (sometime in the mid-late 90s), though only spent enough time with it to learn the home keys. I would then look at the keyboard for the remainder of the keys. Initially that was probably no faster than my old hunt and peck method. I remember remarking at one stage that I was looking at the keyboard out of habit. Then one day I noticed that I was no longer looking at all. I'm sure it was a strange feeling at the time!

Goes to show you don't really need to learn the whole process with some type tutor software. Though in terms of efficiency you may want to be aware of what they suggest. For instance, I think I was hitting the Y key with my left hand rather than right hand at some stage, but long ago changed that.
