Would you get an ipad mini or ipad air if you already have an iphone?

Thanks for the answers. Can't decide which size to get.

If you use it for book reading and movies then I would get the bigger screen.

I agree with the previous user.
I would go with the bigger iPad since it's not much more expensive and I always found it to be better since it can display more content when you are browsing the web etc.

Also I think the small screen of the mini is not a big change if you already use an iphone frequently.
Sure, the phone is just a phone for talking but I'm sure you use it for browsing mails, even at home.
