At 7 I was probably a lot more competant than I am now. My dad was an editor and he's always had top of the range equipment because he's one of the most proficient in his area so he's used to high standards. So I mean, I can remember as far back as when I was 3 being taught how to use stuff, because that's all he's into, so what else would he bond with his kids over? My brother and could operate DoS confidently, although probably not very efficiently, but still; when you're that young you just assume whatever you're doing is what you should be doing, and you apply yourself to it a lot better than you do as you age. When kids acquire a first language, they will have learnt the structure completely by the time they reach age 7. Interestingly if they only commence learning a year or two before this point, they will still have acquired all the basic rules by age 7. And those years are the best to start on second and third languages. So it's probably pretty similar with computer literacy; if you start young enough, you will have the capacity to acquire it as a sort of language. A child of 7 *should* be able to perform more competantly than older people with the same level of experience, because that's how our brains work. Or so I was told in linguistics...It's still impressive though!
