Maybe there's nothing to theorize about that's specific to girls? Sounds like my story, as a guy, and that's a subtle but important point. I used to run every program I could find, copy stuff from friends computers that was new and unfamiliar, borrow books from library/parent's friends, etc. Eventually I stumbled onto BASIC and the rest worked its own way out.
Yet I know plenty of kids - male and female - who had a machine just as powerful as I did (some more powerful), had the same access to information I did, etc. and didn't bother with any of that. Why was I so inquisitive and interested in computers to exclusion of everything else? Why did I spend all day and night on them while other kids were experiencing their first drinks, their first relationships, hanging out together, etc.? That's a more interesting question than the sex one, IMO.
