"Women pilots have an accident rate four times higher than men pilots because of their impaired hand/eye coordination.", according to
http://christianparty.net/sex.htm
However, this site also states that "A profound intellectual gap causes a huge difference between the sexes in how they vote.", "It takes up to 8 1/2 men workers to compensate for the loss of productivity of one unwanted woman worker.", and many other, um, interesting things, my favorite being the groundbreaking revelation: "Forty million women and no men have had abortions since Roe vs. Wade."
Ah, well.
http://www.math.luc.edu/ethics96/papers/caftori.txt tells us that at least "Boys are more attracted to action-oriented, competitive games and
software requiring hand-eye coordination"
And
http://www.fathersforlife.org/dale/genetic.html finally says "The results could also be interpreted to add the massive body of evidence which suggests that rejection by male peers because of lack of hand/eye coordination contributes to a need for masculine acceptance and affirmation, and that this need leads to same-sex attraction. It is also possible that hand/eye coordination is developed through early play experiences with the father and therefore that a boy who did not have interaction with the father would be more prone to lack the experiences which would grow those parts of the brain which control hand/eye coordination.

"Heterosexual men outperformed heterosexual women, whereas gay men threw less accurately and lesbians tended to throw more accurately than their heterosexual counterparts. Differences in sports history or hand strength did not account for these effects."
"Pegboard scores found no interaction or main effect of sexual orientation, but the effect of sex was significant. Regardless of sexual orientation, women outperformed men and this difference remained significant even when a measure of finger size was partialed out. this study provides new evidence suggesting an association between sexual orientation and motor-performance profiles."
"The results of the study are consistent with the notion that early hormones mediate changes in neural functioning that underlie both sexual and nonsexual behaviors in humans. More specifically, the study adds evidence that sexual orientation and motor/cognitive predispositions have early biological contributions."
