The size really is a big thing. This phone feels like it's the right size. The iPhone just feels...small.
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".
