I think you probably got lucky, but you're right that android knowledge is growing and and there now exists a good sized group of people who will specifically seek out an android phone when the time comes to upgrade. But for the large majority of people, their first android phone was purchased because they just wanted a cheap generic smartphone and that meant android. And for the large group of people that is still switching from feature phones to smartphones, android is still the default cheap phone, and iPhone is still the default premier phone.
Windows phone's target market is fans of windows phone, but they are trying to build that group exclusively through advertising. Apple built their market of apple fans through the iPod and other products. Android built a market of android fans through the cheap phones to feed sales of premium android phones. Windows phone needs a feeder market if it wants to be a premium product.
