my experience is that women tend to prefer clickies, and fairly simple. Though given a choice between and ugly clicky and a pretty twisty, they tend to take the twisty. The clicky preon's I have given away have been HUGE hits, as have the ITP A3's I have given out. Last Xmas I gave out a bunch of lights, letting them choose which lights they wanted, and the Preon 2 and ITP A3's were by far the most popular, over ITP A2's in black, or quark MiNis. Sure the Preon's aren't the cheepest choice, but they are really nice for a purse light.
One thing I have definitely noticed, is that women don't want something that you wouldn't consider a decent choice for yourself. If you are packing a 150+ lumen light, and you give them a 10 lumen light, they wont be happy. But if you give them a 80 lumen light that looks nice and works well, they will be very happy.
