1. I've entirely focused on iOS. Not that I am opposed to Android, it's just that there are so many things to learn in tech I haven't gotten around to Android yet. I think you can create high quality experiences on Android as well, but people don't seem to be putting in as much design effort as they do on iOS.

2. I haven't encountered copyright or piracy issues (yet). I'm sure when it happens I will get frustrated at first, but just accept it and move on. I'd much rather focus on teaching and creating new content.
