I wouldn't say *most men* are into keyboards and all that. As quadibloc would say "it's all a plurality, yes indubitably".
So only a few guys/girls are into keyboards. It's a very small minority, regardless of gender (I think anyways).
People who use their hands a lot for delicate things, like art (painting etc), which usually most girls I know do, would probably be interested in a keyboard that suits the fingers nicely.
