I live in Canada and literally everybody in my life, except for one friend who is a huge Android fanboy, uses iOS. I don't have a phone, but I can still iMessage everybody else I know from my tablet except for one person. Now I love the idea of android, I love the technology and I use Linux daily on web servers so I get the customizeability and the appeal, but let's face it - if I write an iOS app I can send that to nearly everybody I know. If I write an android app only one person I know could install it.
