There is a nice Ignite talk by a female Google engineer at http://igniteshow.com/videos/im-barbie-girl-cs-world

She argues that Matell is actually breaking with stereotypes here for a change (though inadvertently)- and that it's a good thing.

I'm not sure if this is exactly the point you're making; but my experience of women in the engineering trade (admittedly more electronic engineering than computing) is that they are fairly "girly".

Certainly not many fit the traditional stereotypes of "girl geek".

I'd say the doll pretty much fits well.
