I like both. I can't stand the argument about games not being on Android. Hello, it's a smartphone.

Nor can I stand the argument about customization not being possible on iOS without a jailbreak. I'm going back to iOS once the iPhone 5S comes out though.
And I like Windows too. But I don't have a use for it anymore after making the permanent switch to OS X in 2006. My usage has completely changed. Linux is nice too, but I've never had a use for it either.
