What's your favourite thing.....about Android?

I'm running my own little social experiment. Well, I think you could call it that.

I'm interested to know what the Apple fanboys in this forum think is the best, most redeeming feature of Android. The one feature that has the potential to switch you from iOS to Android (I'm not saying it WOULD change you, just the feature that COULD change you.) Also, I'm posting a vice-versa post on the Android Army forum.

Note: You're allowed to comment on hardware. It's harder to comment on it when talking about Android, but you're allowed to say something like "My favourite thing is that you can have a choice of phones with different operating systems."

So go ahead, what is your favourite thing about Android?
