I will say that I just switched from a iPhone 4 to a S3 and it seriously makes the iPhone feel like a toy.
How so?
And then the OS. I didn't like the built-in keyboard, so I downloaded and installed another one. Now "keyboard" is just a preference in the settings menu, and I choose which one I want.
But it's a whole lot of small things like that. Android just feels grown up, to me. iOS feels like a sandbox, like something you'd find in a school or something, or "baby's first telephone".
