What OS do you prefer your smartphone to run on?

Now that I think of it, the only people who have revealed their preferences to me are Windows Phone users. Time to clear that up on my part.

It should be rather obvious that I prefer Windows Phones, largely because they work great in conjunction with my T100.

iOS would be a close second, though. (It's polished, and it has polished games on it.)
