I was recently asked my opinion on computers and learning.
Since I don't have kids of my own, I refer them to my colleagues: the CTOs and VP of tech. from very important IT companies. Not a single one allows their kids under age 10 to use a computer. They are read to, and read books, and write with crayons and pencils.
Worried about being behind their classmates? Not at all; any advances pop up so quickly there is no problem.
