Their focus on and uncompromising attitude to human/technology interaction makes their products more usable and powerful tools for more people than Linux, Windows and Android. Android have been making great strides, but it still isn't as intuitive as Iphones. I use Android because I don't mind and I got an Android phone for free from someone who was fed up and bought an Iphone. And my every day computer runs Fedora, but when a relative asks I advice them to get an Iphone and a Mac. I used to have to use Christmas and Easter to fix my relative's computers, now that everyone has Apple products(except my Grandma, and it's amazing what a Pre-WW2 woman can clog up Win 7 with) I don't have to. As a computer nerd it can be difficult to see the significance of this, but this kind of approach needs to be applied to those parts of the Bitcoin eco-system that's aimed at ordinary mainstream users.
