"Bias in Toys": I think there might be more pressure against boys playing with girl toys than vice-versa. Most of them are more aptly "non-girl-specific" toys than "boys toys". The kids generally choose the toys they want to play with, and often a selection is available because of siblings or group care environments. For our purposes, isn't the bias instead the "age appropriate" toys? And how many kids, of any age, would be admonished for trying to take the thing apart rather than play in the intended manner?

Marketing of computer games: I think my niece chooses the games she's interested in based on previous experience with the game and friend's recommendations of what to try, not what's on the cover, which gets quickly lost as the disc's are in an unkempt pile. She'll naturally put in Animal Doctor or Pinada Garden rather than playing Basketball that's already loaded.

I think the effects of the biases, for the purpose of engineering and computer developers, is overstated. this is particularly true for the top echelon Geeks who would do what they were drawn to, in open defiance of sterotyping. But these are even more different, in terms of numbers of each sex.

As for remembering prominant women in computer science, in addition to Ada Lovelace I'm aware of Adele Goldberg and Grace Hopper.
