I tend to believe this snapshot of polled information. My reasoning for believing it is that kids today are born into the computer culture and don't have any thresholds to cross over before they become comfortable with the electronic wonder. They use it as soon as they can understand if you punch a button the following will happen in games. They use computers from kindergarten on.

We older folks at first had to understand that if we pushed the wrong button, the world would not explode, and then it's a slow transition to feeling comfortable with the whole concept. Not to say that older folks cannot become computer nerds, but for kids they're born into it and absorb it like sponges.
