I disagree with this. I work as a teacher at a secondary school. Even the wealthier kids, the ones who I know have computers at home, and often their own laptops that they bring to school, can't use a keyboard to save their life. They're always impressed at how fast I can type (I learned from playing MUDs way too much when I was their age) without errors and how I know all the keyboard shortcuts and such.
