When having the iphone will i use less my ipad mini?

I wanted to buy an iphone 5 when the 5s will be realesd because the 5 will cost less and so i wanted to ask when i buy the iphone 5 will i use the ipad often or it is better to sell it and with the money i get i buy the iphone. I wanted an opinion from some one who have both 5 and the ipad mini which one you use often

Do whatever you want but you can play games on the iPad like farmville & stuff on the bigger screen then on the iPhone

I have an iPhone, iPad mini, and a Macbook and to tell you the truth, I use my iPad when i'm too lazy to open up my Mac or if i'm laying in bed. I use my iPhone to text and send emails when i'm on the go and my iPad stays at home (and my Mac usually if I don't need it for class). They're all very useful and I don't really use one much more than the other.
