Starting conversation with girl?

There's this fantastic girl that sits next to me in diffy-Q. I was sitting there all class today and could not think of a smooth thing to say to her. The prof has assigned us partners to help each other with the math, so there's no reason to ask her math related question.

I thought about the weather, her clothes, her phone, etc but they all seem lame. She had an iphone so that is obviously not noteworthy. She was wearing jeans and a tshirt. Weather -blah.

Any ideas on something clever that would not be too obvious I'm hitting on her to start?

Why release an iphone 6 PLUS?

It's really just a bigger version of an iphone 6. I suppose with improved specs such as better battery life and pixels. But it's bugging me why apple did that, it's kinda the same.

Who would buy the iphone 6 plus? Would you say the tech geeks that likes the whole better specs? It boggles me
