I use Android and Android only. my first smartphone last year ran Android and I've never wanted an iPhone. I really like being able to root, flash custom roms, and customize everything that I couldn't do with iOS or Windows Phone. I also have a lot of paid apps so I wouldn't switch unless Android was dead, which won't happen as it's the dominant force in the Smartphone world due to its flexibility and adaptability.
I've used iOS a few times and it just doesn't appeal to me. I just don't like not being able to customize. My iPhone would be just like everyone else's. And no home screen widgets? No thanks.
