Presumably (just guessing - not my area), there is a similar sized core of male and female buyers who just want the tech at any price. The rest is made up of predominantly males who are interested but not as committed, and they drop away as the price rises. I think the majority behave as generally expected, but that core is surprisingly gender independent. Of course, it may be that I haven't a clue what all these charts mean!!

Perhaps women just like stuff that is expensive
