I took one in high school too, it was a choice between typing and woodwork. Most boys took woodwork, I knew I would need it for computers one day and I'm glad I did.
I also don't have problems with the characters that were not part of the lessons. I spent about 10 years on a US keyboard layout and then another 10 with a mostly UK keyboard layout, and then there's the UK Mac keyboard which is a strange combination of the two. I don't feel I have trouble switching between the types of keyboards, it's like switching between driving on the left and right hand sides of the road which I also got pretty used to.
