I am on other sites (knitting and scrapbooking) where women go crazy to buy products if they are available in pink.
I can see where maybe tech products wouldn't be in the same market because those same women are, for the most part, not interested in readers the way they are now. They are interested, but do not wish to spend the money for one until a truly universal format is established. What I've been seeing is that they are all concerned that their chosen format is going to go the way of Betamax and 3 1/2" floppies, and they don't want to be stuck with books and files that can't be read. Most people -- me included -- are not going to spend time and energy format shifting and managing libraries when that time can be better spent on picking out patterns and planning layouts.
They may jump on a pink tool that they were already going to buy, but decide to buy something just because it's pink? Not likely.
